Radiation Tolerance TestsRadiation Tolerance TestsRadiation Tolerance TestsRadiation Tolerance Tests
Measure Single Event Upset (SEU) and Total Ionization Dosage (TID) effects with 63 MeV proton beam at UC Davis.
Measure effects due to Displacement damage of bipolar and biCMOS with 1MeV neutrons at OSU.
Results:• Negligible degradation of analog performance due to
TID (>10kRad) or displacement (2x1012 cm-2 neutrons).
• No latch-ups observed up to p fluence of 2x1012 cm-2.
• SEUs in FPGAs observed and cross sections measured. All SEUs recoverable by reloading FPGAs. SEU rate at peak LHC luminosity manageable for CFEB, but higher for ALCT.

SummarySummarySummarySummary
• Nominal rate of chamber production at FNAL achieved. Chamber production on schedule.
• FE electronics production started; first cost experience positive.
• LV-regulators and trigger boards on the critical path; defines beginning of assembly at FAST sites.
• Endcap infrastructure designed; installation fixture exists.
• Adequate base program support is critical to maintain the schedule.
