Task A Budget Description

The total DoE Task A budget in FY2006 is $1,270,000. This amount includes non-

base funds of $45,000 for support of Chapman's research leave at CERN and $50,000

for support of Michigan's Tier-3 computer equipment. Based on the 'balance' of the

Task A account in May 2006, and using the same spending profile in 2005 to project

the residual of the Task A fund by Oct. 31 2006, we expect that our budget would be

overrun by about 1.7% of our total 2006 funds.

The Michigan ATLAS group also received $522,000 non-operating funds from DoE

and NSF for ATLAS muon detector M&O (Maintenance and Operation) funds in

FY2006. Such funds apply to specific items in the WBS (work-breakdown-structure)

of the projects and are controlled by the Program Project management.

In FY2007, Task K will transfer 0.5 month summer salary for both Jianming Qian and

Homer Neal to Task A, Task K will also transfer a postdoc (J. Strandberg) support to

Task A. Task C will transfer 0.5 month summer salary support for Dan Amidei to

Task A, and 0.5 graduate student (Andrew Eppig) support to Task A. Based on DoE

2007 budget guidance for Task A, we made our 2007 personnel support plan as

included as Table 1 of this document. For comparison purpose, Task A 2006

personnel support is also represented in Table 1.

Scientific personnel support for Task A in FY2007 will include 9 month summer

salary support for faculty (Zhou, 1.5 month, Neal, 2 month, Chapman, 2 month, Thun,

2 month, Qian, 1 month and Amidei 0.5 month); 57 month salary support for 5

research scientists (Diehl, Goldfarb, Levin, McKee, and Zhao); 24 month postdoctoral

salary support (Burelo, Cirilli, and Strandberg); 16 month engineer salary support

(Ameel, Dai and Weaverdyck); 4 month salary support for a computing project

associate (Herr); 6 month secretary salary support (S. Wilson); and 18 month

graduate student salary and tuition support (A. Eppig, A. Wilson and N. Panikashvili).

Chapman and Thun have been resident at CERN to lead the endcap muon detector

Phase II commissioning and system integration. Zhou finished Muon Phase I work

and returned to Michigan from CERN last August. She is in charge of establishing the

Muon Calibration center at Michigan. Neal continues to lead the US ATLAS

collaborative Tool project. He also played a leading role at Michigan for grid

computing R&D and for developing the Michigan/MSU Tier-2 proposal. Amidei is

working on the gauge boson Z' detection using the muons with his graduate student

Andrew Eppig and Qian has begun work on B-physics studies and Higgs searches.

His new postdoc Strandberg will join him on July 10, 2006 for Higgs search studies.

Our research scientists continue play leading roles in many different ATLAS research

areas. Zhao was the Phase I project supervisor in Building 184 at CERN, he will be at

CERN to serve as Phase II Big-Wheel (A-side) assembly and test supervisor in

Building 180. McKee continues to lead the high-speed network R&D work for

ATLAS through NSF research programs: UltraLight (ITR), GridNFS (NMI), and

TeraPaths (MICS). He has served as PI for a joint Tier-2 proposal by UM and MSU.

If the Tier-2 proposal is accepted by US ATLAS, McKee will serve as a co-director in

our Tier-2 center. Levin has been the co-coordinator of the ATLAS physics group for

combined muon performance. He has also been a major physicist at CERN to

supervise the students for the Phase II commissioning work. He will play an

---

important role for software development in the Michigan muon calibration center.

Diehl is in charge of software setup for the muon calibration center. He also manages

the Phase 1, 1.9 detector commissioning DataBase. Goldfarb coordinates the ATLAS

Muon software development at CERN. Burelo, our postdoc, has concentrated on

Λ

b

polarization physics studies at CERN, and Cirilli has been the ATLAS muon software

database coordinator. Ferretti is in charge of Phase 1.9 and Phase II commissioning

data at CERN, he also helps to maintain our computer file servers for commissioning.

Commissioning data is processed by him to produce the DB contents.

Weaverdyck is our mechanical engineer and is a major contributor to tasks of

chamber installation tooling design and fabrication. He is also in charge of building

the gas monitor chambers. Dai is a scientific engineer, resident at CERN. He is in

charge of the data taking DAQ systems and software. He will be the Phase III endcap

detector commissioning leader. He is also the major person in our group managing the

mass production of MC physics events. Ameel is an electrical engineer, who provides

electronic module construction and testing. Ball is our major engineer for the CSM

development and testing. He is now our computer cluster (UMROCKS) manager.

Gregory is a part time engineer who provides CAD designs and readout software for

testing. Graduate students, Eppig and Wilson are helping our hardware project in

Phase I and Phase II commissioning. They also deeply involved in ATLAS physics

studies to prepare their Ph.D. thesis topics. Panikashvili is partially supported by

Michigan group. She is studying

Collaborative Tool funds

support

We request computing equipment funds of $50,000 in our FY2007 budget. In

addition, the university has committed $100,000 in matching funds for the computer

hardware.

We request a total of $165,000 for travel in FY2007. Michigan has the largest

complement of personnel resident at CERN for muon detector work. The installation

and commissioning work is crucial if the muon endcap is to be installed when the

LHC turns-on. The requested travel support is based on our past three years

experience working at CERN.

We put the same level of the funds ($58,000) in our FY2007 request as in FY2006

budget for materials and consumables. The funds will be used at CERN ($20k), at

Michigan ($18k) and for the Electronics shop ($18k).

---

The indirect cost of the University of Michigan high energy physics grants are set at

the off-campus rate of 26%, which applies to salaries, benefits, travel, materials and

supplies, but not to equipment and to tuition.

The total Task A budget request for FY2007 is $1,395,000. Other details of the Task

A FY2007 budget are given in the Task A budget sheet.

Finally, we would like to put a high priority request to DoE to fully support our

graduate students, Alan Wilson, Andrew Eppig and John Purdham (total 24 months)

from DoE Task A funds. The major support, at the moment, for these excellent

students comes from US ATLAS M&O funds. As the LHC approaches beam

collisions, they will focus on physics analysis for their Ph.D. thesis work. DoE's

support will be crucial next year. The salary and tuition cost needed will be about

$85,000.

Introduction

This report describes the progress made during the past year by the University of Michigan ATLAS

group and outlines plans for the upcoming year. Our group is one of the largest in ATLAS,

enabling us to make major contributions in many areas of the experiment. We are heavily involved

at CERN in the assembly and commissioning of endcap muon sectors and will participate in the

next phase of this activity as the sectors are integrated into the overall detector in the ATLAS

cavern. We continue to be active in software service tasks, including overall muon software

coordination, the establishment of databases for all aspects of the muon system, and the

coordination of combined muon information derived from all ATLAS detector systems for optimal

physics analysis. At Michigan we have begun the establishment of a muon calibration center and

continue to strengthen our existing computing infrastructure in support of this and other ATLAS

computing activities. We recently submitted a strong Tier-2 proposal to serve the needs of ATLAS

and to allow us to carry out our muon calibration responsibilities. Members of our group continue

to be involved in grid network R&D, innovative collaborative tool development, and muon

electronics upgrade activities. Finally, we are active in a number of physics analysis projects

including Z and Z’ studies, diboson production, and

Λ

b

polarization.

We present a final note regarding the need for additional funds to support the very intense

installation and commissioning activity at CERN while supporting graduate students in preparation

for ATLAS physics. In the submitted budget we have placed $150K of foreign travel. This amount

will be needed if we are to meet the very aggressive schedule set by CERN management. Support

for Graduate Students has been sacrificed to make this possible. We anticipate a supplemental

request of $50K to restore partial base program support for training future scientists in the field.

Commissioning the MDT at CERN

J. Chapman, T. Dai, A. Eppig, C. Ferretti, D. Levin, J. Purdham,

R. Thun, C. Weaverdyck, Z. Zhao, and B. Zhou

The University of Michigan group has made important contributions to this effort in several key

areas. Curtis Weaverdyck designed and implemented some of the MDT chamber handling fixtures

critical for mounting chambers on the sector structures. Bing Zhou and Ed Diehl participated in

setting up the infrastructure for the sector work in B180. Jay Chapman is leading the group that

provided the data-acquisition systems for testing all MDT chambers before and after their

incorporation into sectors. In May he completed a one and a half-year stay at CERN where he

played a critical role in initiating and supervising the B180 work. Tiesheng Dai and Claudio Ferretti

are now continuing the day-to-day testing of sectors in B180 and will also perform this work in the

ATLAS cavern when sectors are moved there. Manuela Cirilli and Claudio Ferretti continue to

ensure that the MDT commissioning data are transferred to the relevant ATLAS databases.

Graduate student Andrew Eppig has assisted them in this effort by taking complete responsibility

for updating and making available raw data recorded in so-called sector “travelers”, documents

attached physically to each sector. Rudi Thun joined the B180 activities full-time in January, the

beginning of his seven-month sabbatical at CERN, and has taken responsibility for fixing general

chamber problems and for all aspects of implementing the optical fibers on the sectors. The latter

proved to be a challenging task since some of the early fibers, provided by an Israeli company,

---

failed unexpectedly after installation. Jay Chapman, Andrew Eppig, Rudi Thun, and recently

graduate student John Purdham have all done hands-on work in connecting various services to the

MDT chambers on assembled sectors. Dan Levin, though primarily engaged in muon software

work as coordinator of the Combined Muon Performance task, took on the responsibility of setting

up and operating the systems for feeding chamber gas to the sectors in B180. He has also

participated regularly in diagnosing chamber problems such as high-voltage trips, broken

connectors, and open connections.

The commissioning effort in B180 has been very successful and become largely routine thanks to

the dedication of all those directly involved in this work. We have faced a few unexpected

problems such as the fiber failures mentioned briefly above and the discovery of unrepairable

electrical shorts in a few MDT tubes. Surgery on one of these tubes led to the discovery of a sense-

wire fragment left inadvertently in the tube during the wire-stringing process. This wire fragment

bridged the tube-wall and intact sense-wire only after the chamber was re-oriented from a

horizontal to a vertical position during the sector assembly process. It lay in a harmless position

during all prior testing.

Looking forward, we note that the work in B180 will temporarily increase as we tackle the

challenge of assembling the sixteen “MDT Big Wheel A” sectors. The reason for this is the extra

step of performing the so-called “Phase 1.9” commissioning work on the eighty “A” chambers.

This includes the addition of B-field sensors and performing various other checks. For the “C”

chambers this phase was already completed last year in CERN B184. Zhengguo Zhao will move to

CERN for one year beginning in July to supervise the Phase 1.9 work as well as all the other

Michigan activities in B180. He will be helped full-time by Tiesheng Dai, Andrew Eppig, Claudio

Ferretti, and Manuela Cirilli. The completion of the “A” sectors is expected by the end of

September.

Michigan will play a major role in the

testing of sectors after their move to the

ATLAS cavern and in the subsequent

testing of assembled MDT wheels. The

organization of how we do this work and

the coordination with other ATLAS muon

groups is currently under intensive

discussion and planning.

Testing in the cavern will indeed be

challenging since the sectors will first be

located on the HO structure with their

readout connections spanning the 40 meter

height and width of the Big Wheel as seen

in Figure 2 to the left.

Electronics Development for MDT Readout

J. Ameel, R. Ball, J. Chapman, T. Dai, C. Ferretti, and J. Gregory

Michigan was charged with the manufacture of the ATLAS MDT readout multiplexer (CSM-4),

with the certification of the overall front-end design, with the commissioning of the US built

chambers in the muon endcap, and with building the production and commissioning databases for

the muon endcap. In addition, we have provided the ITEP Russian team with facilities, procedures,

and database recording systems to complete the endcap EO chamber certification. We have also

provided the manpower to assemble and transfer the Russian chamber data to the database server.

In addition, we have written and provided key software to initialize the multiplexer, collect and

examine the data for both the endcap and barrel MDT systems.

During the current year, Michigan completed the production and distribution of all 1325 readout

multiplexers and their passive interconnect motherboards for the full muon MDT system. Testing

has proven that the design is solid and reliable when reading data from the Harvard-KEK

mezzanine cards at the designed bit rate of 40MHz and when running at the designed output word

rate of 25MHz. The yield of fully functional boards is ~ 90% of the manufactured units. Some ½ of

the faulty boards will likely be repairable. The remaining 40-50 boards are expected to be more

costly to repair than to replace. This work included radiation testing of the design for total ionizing

radiation resistance and for single event upsets. The board survived at the dose corresponding to

10 ATLAS years at full luminosity with a safety factor of more than 10; 5 for the uncertainty in the

ATLAS dose and 2 for process variations in the chip manufacture. Two features of the Xilinx chip

were employed to mitigate the effects of single event upsets, Triple Modular Redundancy, and

scrubbing of the configuration. The code for chip scrubbing was supplied from Xilinx and has not

successfully functioned to date. This is proprietary code and Xilinx is committed to its preparation.

This code rewrites the configuration RAM continuously, being careful to skip over the working

registers so that the chip continues to operate normally.

During the current year, Michigan also assembled and tested 2400 cables that connect the passive

motherboard to the NIKHEF supplied slow controls system and provided 16 ultra reliable current

and voltage protected 5 volt power supplies for the test fixtures.

A subtle design fault, discovered in the KEK TDC chip, has prohibited the use of pair mode

readout. To retain the same luminosity reach when forced to select edge mode output from the TDC

(doubling the data to the multiplexer), we have increased the bit rate from the TDC to 80MHz. This

increased data flow demands that the output rate of the multiplexer also increase if pileup is to be

avoided. The reliability of this doubled data transfer between the TDC and the CSM-4 has been

verified and will now become our baseline standard. Doubling the output speed has been tested

successfully with the CERN designed Filar card (the unit we use for testing) but is marginal when

the multiplexer sends data to the NIKHEF designed MROD-X. The problem has been traced to

inadequate clock stability. To insure sound operation at 50MHz, a small (~1.5cm x ~1.5cm) add-on

board for the CSM-4 which contains a 50MHz crystal, has been designed. This precise crystal

clock will eliminate the need to multiply the slower crystal clock, a process which leads to

additional jitter. The small crystal board has been tested and proven effective.

---

We now face the challenge to produce these small boards and to install them on the multiplexers

already in service at CERN. Because the boards are so simple, production cost and schedule will

not be problematic. Installation and recertification will, however, be manpower demanding at

CERN. We have begun discussions regarding plans for incorporation of this modification both

within the US muon endcap community and with the non-US community. We are lucky to be able

to double the speed at which the system runs. It is a credit to the designer of the CSM-4, Robert

Ball, who placed unused inputs to the FPGA on a pin header that can accept the add-on board and

who provided a conservative design that could be run at twice the speed initially envisioned.

Most of the work at CERN is described in the commissioning section above. One aspect that relates

specifically to the electronics group, is the development and use of the readout test fixtures and to

the software that runs on these fixtures. The high performance readout demanded by the LHC

environment is not simple to test even though the hit rates are modest in the assembly area. Each

multiplexer contains a gigabit output link, ~1000 bits of setup information, and ~100 sensor

readouts representing temperatures, voltages, and b-field readings. The test fixtures contain a Linux

PC that reads the gigabit links, a Windows PC that controls the setup and sensor readout, and a

VME controller housing the CERN Trigger Timing and Control modules. Michigan has assembled

and programmed 7 of these systems. Two are used in building 184 by the Russian team for EO

chamber testing, 3 are used in building 180 for BW large sector, small sector, and EIL4 testing, one

is used in Ann Arbor for CSM-4 checkout and development, and one will be used in the pit for

sector recertification when they are mounted on the H0 structure. These are Michigan assembled

systems and we are committed to maintenance and modification (to 50MHz) of them.

Muon DB Development and Coordination

Manuela Cirilli, Edward Diehl, Claudio Ferretti, and Shawn McKee

Manuela Cirilli was appointed ATLAS Muon Database Task Leader (together with Joe Rothberg,

University of Washington) in July 2005. The ATLAS Database and Data Management project

covers the development and deployment of the software necessary to operate the databases holding

the following types of information: detector production and certification, detector installation,
