2. Testing Facilities Readiness
Clean room adjacent to production area
Room layout finished
Currently in high bay with intentionally same layout
Missing only hybrid thermal cycling test
Clean room will be finished in April
Storage cabinet with dry air flow in place for testing phase
Long term module storage cabinets under construction at KSU

ARC Test Results (1)
Raw Noise
1 Prototype Module Tested
Module testing in UCSB clamshell decreases common-mode noise to the point where sensor-sensor opens become detectable by their lower noise levels

5. UCSB Status-Anthony Affolder
ARC Test Results (2)
5 hybrids tested on arrival
All good, but fail current requirement given in the Procedures for Module Testing
Pedestal test reproducible, but noise measured very sensitive to digitization effects
Measured noise varying the pedestal by changing VPSP value
Digitization effects cause variations larger than ±20%
See hep.ucsb.edu/cms/cmsUCSB.html for more complete description

6. UCSB Status-Anthony Affolder
ARC Test Results (3)
4 hybrids have had APV bonded to pitch adapters
All channels are good
Hybrid clamshells enable testing without large pickup effects at chip edges
Hybrid isolated with plate and lid grounded
Same requirements can be made for hybrids with or w/o PA bonded

7. ARC Test X-calibrations
Minimal X-calibration has been performed
Same faulty channels found at FNAL/UCSB on prototype model
CERN FHIT/UCSB ARC test compared
Pedestals very similar
Noise is slightly higher than CERN FHIT measurement
Not understood if it is FHIT/ARC difference, a software difference, an environmental difference, or a digitization effect
Once model production begins, plan to exchange modules with FNAL for X-calibration

ARCS Database
No entries yet put into official database
Waiting for ARCS interface for database upload
All testing results have been made available to silicon community on local website

DAQ status
1 full DAQ stand available at UCSB
Planned only for Vienna box tests with modules
Limited number of tests performed
Focus on bringing up hardware/software for Vienna box
Xdaq, LT, and Xrod software all compiled and run
Still working to understand controls/output
No LED stand planned for DAQ
No database work done as of yet

Vienna Box Status
Vienna Box recently arrived at UCSB
No modification necessary to use with TOB module carrier plates
Full compliment of plates currently in machine shop
LV distribution ready
Just received HV controllers (both the A128HS and A1303)
Integrating as fast as possible
Demonstrated each slot works with hybrids
Thermal cycled box between –25 to 30° C with chiller
Need hardware to test more than one channel at a time
