The LHCb Silicon Tracker:
Radiation Damage (TT):
minimize R/O channels & radiation length:
large pitch O(200mm)(charge collection)
long strips 33cm (noise)
“thin” sensors (little charge)
40MHz, fast readout (noise)
signal remainder 25ns after peak specification: remainder < 0.5 (TT)
< 0.3 (IT)
Radiation Damage (IT):
Production tested on 4 IT and 7 TT modules so far, almost ready for full production !
