Lucien Cremaldi, Frank Hartman, Umesh Joshi, Simon Kwan, David Sanders, Ping Tan, JC Yun
discussed how to handle the offline database.
Frank said the Tracker is not considering store any CAEN high voltage information during a run
other than the Status information. He
said his experience with CDF silicon system backs this. Voltages and currents of Tracker channels
will stored in the offline database at the beginning and end of a run. FPix group did not
make any decisions on this yet.
produced a table showing temperature drops when there is an
air gap exist when de-lamination happens. Please look into his table, DocDB #892, which is called ‘Thermal drop model
for FPix blades’.
Simon promised to
provide updated input values so Lucien can update his table.
said there is a document on humidity sensor measurement before and after the
irradiation. He asked the DCS group to
study and report the results. This is DocDB # 449 which is titled
‘HMX2000 Calibration Data’. https://docdb.fnal.gov/CMS-private/DocDB/ShowDocument?docid=449
