PROPOSAL FOR FUNDING

UNIVERSITY OF MICHIGAN
University of Michigan Atlas Project

1.0 Overview
The Large Hadron Collider (LHC) being built at the European Organization for Nuclear
Research will represent the premier tool in the world for the exploration of the new fron-
tiers in particle physics when it is completed approximately five years from now. With this
facility we expect to be able to address many fundamental topics concerning the origin of
particle masses and composition of matter at the sub-quark level.
Twelve members of the University of Michigan High Energy Physics program (Bob Ball,
Jay Chapman, Ed Diehl, Myron Campbell, Steve Goldfarb, Dan Levin, Shawn McKee,
Homer Neal, Jianming Qian, Greg Tarle’, Rudi Thu, and Bing Zhou) have committed to
the ATLAS and are working on various aspects of the forward muon detector develop-
ment. Michigan joins the Boston Muon Consortium and University of Washington in this
effort. The Michigan work will focus on two aspects of the detector development, the con-
struction of the largest MDT tubes and the development of front-end electronics for these
and other MDT tubes of the system. Rudi Thun is directing the tube construction project,
Bing Zhou the chamber production, and J. Chapman is leading the electronics develop-
ment aspects of the project. Other members are engaged in computing aspects of ATLAS
not covered by this proposal. Homer Neal leads these computational projects, databases,
collaboratory development, and networking.
For 1998 the US ATLAS collaboration has initially provided a modest $62K of ATLAS
detector funds for Michigan. A second allocation of funds to Michigan in 1998 was pro-
vided as a direct contract to Michigan from Brookhaven. With this second allocation, the
total provided to Michigan for 1998 was $316K. The third allocation of funds for 1999
totaled to $715.7K and represented the first full scale operation of the detector construc-
tion program at Michigan. This proposal is for continuation of the construction of cham-
bers and for the continued development of readout electronics for the 10K channels of the
ATLAS front-end electronics. Michigan has coordination responsibility for the 10K chan-
nels test. The Task A proposal submitted as part of the University of Michigan base pro-
gram presents the specifics for these projects. The deliverables and dollar specifics are
contained in the attached Amendment to the Memorandum of Understanding between US
ATLAS and the University of Michigan.
2.0 ATLAS MDT construction task at UM
The University of Michigan will be responsible for the R/D, prototyping, construction and
testing of 104 "Monitored Drift Tube (MDT)" chambers in the forward muon spectrome-
ter (chambers EMS4, EMS5, EML1, EML3, EML4, EML5, EEL2). These 104 chambers
require the construction of more than 40,000 drift tubes over the next 4 years. Our efforts
include the design, analysis, manufacture, quality assurance and quality control of the drift
tubes, their assembly and alignment in chambers, and chamber environmental services,
quality assurance, as well as delivery to CERN for installation.

The drift tube assembly station for automatic wire stringing, tensioning and crimping,
endplug insertion and crimping, tube length measurement, wire tension measurement, leak
testing, wire position measurement, and dark current testing is complete. This station has
already been used for the production and testing of 400 tubes for module 0 (EMS5 cham-
ber).
The chamber assembly station consisting of 21' granite table with 20 microns flatness in a
temperature/humidity-controlled room, with overhead crane, and high capacity vacuum
system has been completed. Tooling for chamber assembly (combs, stiffback, sphere
blocks, spacer frames assembly table, glue machine) is undergoing final assembly and
setup.
We are planning for a May 1 site review by the ATLAS muon management to approve our
production site. We will assemble module 0 during May, 2000, and then move directly
into series chamber production. We expect to produce 10 chambers during 2000.
In addition to the ATLAS project FY00 funds (total $517.5) requested in the table below
(ref. MoU 2000 between UM and BNL), the US ATLAS project management has also
approved $85,000 per year from the DoE ATLAS funds for the support for David Kouba,
a senior technician, who will be responsible for chamber production. The total project
funds for Michigan in FY2000 is $602.5k.
3.0 MDT Electronics
The MDT chambers will be fitted with cards, HedgeHog Cards, that provide the chamber
connections and accept daughter cards, Mezzanine Cards, that contain Amplifier-Shaper-
Discriminator, ASD, circuits and Time Digitizer circuits, TDCs. The remaining on-cham-
ber element in the front-end electronics chain is the Chamber Service Module, CSM,
which connects to as many as 18 Mezzanine cards and communicates to the Tower Sum-
mary Crate, TSC, located in the Underground Service Area, USA-15 where personnel can
be present during running. Members of Michigan’s ATLAS team have updated the speci-
fications for the readout sequence of the ATLAS muon system. A VerilogHDL specifica-

tion of the CSM has been completed at Michigan and the first prototype, called the CSM-
0, has been fabricated and bench tested. In the upcoming months the prototype will be fur-
ther tested and 25 Revision B copies made for use at the various chamber construction
sites. A special version of the FPGA code is being developed for the CSM-0 to permit it to
do tomographic x-ray histogramming at the CERN chamber testing facility. Operation of
the CSM-0 at the CERN test beam is also anticipated during the Fall of 2000.
3.1 Concluding Remarks
The University of Michigan High Energy program has established a significant role in the
CERN ATLAS experiment. We have developed one of the 3 sites for forward muon
chamber construction and are rapidly approaching parity with the other sites begun years
earlier. We have accepted the coordination responsibility for development of the 10K
channels of the ATLAS muon front-end electronics and have designed the readout mod-
ule, the CSM-0, for chamber certification and for use at the CERN test beam. We antici-
pate providing copies of this module to the construction sites for chamber testing in
Summer 2000. Michigan scientists have become major contributors to US ATLAS.
