UCSB Testing Status Anthony Affolder (for the UCSB module testing group) Current testing infrastructure Test results Module test equipment needs Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

Current UCSB Testing Setup 3 ARC Controller + 5 new ARC FE 1 Hybrid testing (2 Hybrid clamshells) 2 Module testing (Module clamshell) LED system DEPP HV supply 1 DAQ system Module Burn-in (Vienna Box) See P. Gartung’s talk Status of testing equipment kept up to date at hep.ucsb.edu/cms/cmsUCSB.html Hybrid Clamshell ARC crate DEPP ARC Controller Module Clamshell LED Controller Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Recent Infrastructure Projects Hybrid holding plates Matches hybrid thermal cycling test stand Can bond and test with low noise in same holder Burn-in low voltage distribution crate LED indicators and fuse protection Crowbar HV protection circuit 12 each for FNAL/UCSB Module cold plate Attaches to current module holder Hybrid Clamshell Module Clamshell Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Testing Status-Anthony Affolder Testing Facilities Clean room adjacent to production area Room layout finished Currently in high bay with intentionally same layout Clean room will be finished in April High Bay (Ground floor) Rod assembly/burn-in Convenient access to loading dock Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Testing Status-Anthony Affolder Test Results (1) 5 hybrids tested on arrival All good, but fail current requirement given in the Procedures for Module Testing Digitization effects cause variations larger than ±20% Hybrid noise requirements should be changed Ni within 50% of average 0.3 < Ni < 1.5 Removes chance of chips with uniformly low/high noise from passing requirements See hep.ucsb.edu/cms/cmsUCSB.html for more complete description Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Testing Status-Anthony Affolder Test Results (2) 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 Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Testing Status-Anthony Affolder Gain Measurements (1) Multi-point gain added to ARCS 6.0 beta software Thanks to the Aachen group Tests are very quick and have advantages over pulse shape measurements More uniform More stable Gain linearities Gain variations Strongly suggest that test be all to all M800 production. Will be included TOB testing Make requirements on gain slope, offset and fit c2 Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Testing Status-Anthony Affolder Gain Measurements (2) 2 of 24 chips so far have no response with low injection values Only occurs in peak mode inverter on Caused by initialization defaults in ARCS tests VPSP set too low Thanks to T. Franke and M. Raymond for help VPSP setting will be modified in new release Removes all seen irregularities Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

Current Estimated Testing Through-put Hybrid Arrival Testing 24 Hybrids per day Matches peak production (+ contingency) Requires dedicated tech Module Basic Test 2 ARC LED stands but only 1 hybrid-to-utri version D XX Modules per day Module Burn-in (Vienna Box) See P. Gartung’s talk for details Lack of hybrid-to-utri adapters limits testing through-put to 1 While burn-in test underway, no module testing possible Module Characterization test will be done at beginning/end of test cycles ARC After Burn-in Test Not clear how much ARC testing necessary after burn-in Depends on grounding/pickup issues LED is minimal test Time estimates do not include database entry. After finishing test equipment acquisition/integration, database will be first priority. Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder

UCSB Testing Status-Anthony Affolder Current Testing Needs Module Burn-in Will not begin large scale production without module burn-in capability Recent shipment to US meets most hardware needs Thanks to all involved Second Vienna cold box scheduled to arrive in early April hybrid-to-utri adapters and the Torino interlock box biggest needs See P. Gartung’s talk Module Testing IV scan, database input Hybrid Characterization Database input Hybrid thermal cycling box Lack hardware/software Tests will be performed by A. Honma’s group for M800 Will aid in manufacturing of test stand Rods Begin to assemble necessary infrastructure for rod assembly/ burn-in Xrod software package already compiled and running Module Testing Meeting March 7, 2003 UCSB Testing Status-Anthony Affolder
