1. University of Wisconsin
Muon System Progress
Dick Loveless
University of Wisconsin
Upgrade Workshop
7-10 November 2011

2. RE4 Scope

3. Bakelite Panels Characteristics Procurement Relatively porous material
Need well-defined resistivity 2-6 x 1010 ohm-cm
Sensitive to temperature and humidity
Procurement
Previous supplier out of business
Testing many new vendors and bakelite variations
Resistivity changes over time
Now have a preferred supplier - Puricelli
Re-established bakelite production sequence:
QA at Pavia, cutting at RIVA, cleaning at GT

4. Bakelite Resistivity
Bakelite production should be finished by early 2012

5. RE Upgrade Assignments

6. RPC Labs in B904
Good progress on building the clean labs in B904
Lab infrastructure (gas, air-conditioning, power) should be finished by early 2012

7. CSC Upgrade Scope Scope Original design unfinished – ME4/2 not built
72(67) ME4/2 chambers to complete system
Increase redundancy of system – 3 year run without access to do repairs
Efficient triggering at high luminosities
New digital CFEB boards for ME1/1 (part of M&O)
Increased capacity for data rate
Ungang the ME1/1 strips – 7 CFEBs per chamber instead of 5
72 New Datamother (DMB) boards
Replace of 72 ME1/1 Trigger Mother Boards (M&O)
Improve triggering for h = 2.1 to 2.4

8. Plan for Production Assembly in B904 factory at CERN
~1000 m2 space with good services (power, gas, etc.)
CMS has allocated this area for the CSC production and provided significant infrastructure
Shipped tooling from Fermilab
All items assembled and operating
Set up CSC factory during 1st half 2011
Armando Lanaro is the factory manager
CMS has allocated ~ 1-2 FTE techs to help us
Good participation by Russian, Chinese groups
Now constructing 3 prototypes

9. January 2011
June 2011

10. Mounts for both RE and CSC
Finished making 133 mounting posts
Identical with existing mounts
Shipped to CERN last week
Install on YE3 during Jan-Feb 212

11. Pre-production Status
Use existing spare parts
Enough for almost 3 prototypes
Factory fabrication
All panels glued, wire-wound, soldered
Factory equipment working fine
Status
One chamber completely finished (gas-tight, low HV current) and in 2-month HV test
One chamber finished without frame
Frame pieces from new vendor will ship soon
One chamber awaiting assembly
Spare chamber refurbished and operational

12. Winding Panels
About μm thick AuW wires are wound on the anode panel with a ~3.16mm pitch. Total wire length ~2600 m per panel. Winding time: ~4h per panel.
9 panels have been successfully wound

13. Automatic Soldering
Automatic wire soldering is done using the Panasonic machine. It is fully operational and has been used to solder most of the 8 wound anode panels.

14. Assembly of 1st new CSC

15. Long term test of 1st CSC

16. Production Status I Honeycomb panels Chamber & Integration parts
Vendor failed to deliver pre-production samples
CERN cancelled the contract in September
Fermilab issuing new contracts this week
Expect first panels at CERN by Spring ‘12
Chamber & Integration parts
All remaining parts ordered, most delivered
Validation of parts in progress
On-chamber cables
AFEB, CFEB cables ordered from previous vendors
LV harness parts ordering in progress

17. Production Status II On-chamber Electronics
AFEB boards (read out wires)
Have sufficient ASICs from original production
Have many spare AFEB boards, need only ~750 (~40%)
Good quote from previous vendor, issue contract soon
CFEB boards (read out strips)
Enough spares for one endcap
Use boards recovered from ME1/1 for 2nd endcap
ALCT boards (anode trigger)
Mezzanine board FPGA: Virtex-E(orig) vs. Spartan-6
Costs: Virtex-E $735 vs. Spartan-6 ($230)
Look-up tables: Virtex-E 9.6K vs. Spartan-6 (92K)
Plan: use Spartan-6, build enough for ME1/1 chambers too

18. Chamber Testing FAST site (Final Assembly and Testing)
Add cooling plate, electronics, strain reliefs, and covers in B904 factory
Perform final tests using CMS DAQ system
Requires modifications of existing software
Build test stand using production electronics
Run a standard set of tests similar to the original FAST site testing
Status
Software modifications of UXC DAQ code begun
Hardware being assembled
Computer ordered, shipped to CERN
FAST site operational in early 2012

19. ME1/1 Electronics Upgrade
Accomplishments
R&D prototypes completed for Trigger Motherboard (TMB) Mezzanine and Digital Cathode Front End Board (DCFEB)
DCFEB prototype tested with CSC in Bat. 904
TMB used as platform for radiation tests (SEU) of components at TAMU cyclotron
EMU Connector card assembled for tests of optical communication
Prototype FF_EMU ASIC prototype completed, tested
New Low Voltage Distribution prototypes designed, fabricated
Installation mockup, mechanical and cable specifications

20. Summary RE Upgrade CSC Upgrade B904 clean labs mostly finished
Bakelite procurement underway
CSC Upgrade
Factory operational, experts are trained
1st preproduction chamber finished, under test
Other preproduction chambers nearing completion
Procurements of parts, electronics, cables, etc. going well
Panel production now seems on-track
