Calibrations
Expected value for most important registers in DAC Counts
CAL LAC : 15-20
CAL FLE : 15-20
CAL FHE : 15-20
CAL ULD : 15-20
CAL FHE : 15-20
TKR DAC : 15-20
Timing
The values shown below are based on the LAT Alignment and we will use these as default for CU tests. Note that this is for the flight configuration B2 that became LAT701 config. TEM diagnostics are not enabled and they will change these values.
Below is a timing diagram that explains how knobs are set to ensure charge is collected at the peak for all 3 detectors. Note that CAL beling the slowest its TREQ Delay is set to 0, while ACD being the fastest detector has more delays added.
CAL Energy Calibrations
Includes results from calibrations prior to CERN
Analysis of muon data taking in the CPT runs is included here
Also dedicated muon runs results are found here
CAL CPT Charge injection runs
Includes data analysis results on all charge injection runs, table generation etc...
Baseline Data Taking
The baseline definition for the registers used for data taking is found here.Finally there are some plots from trigger jitter from Martin Kocian!LAT trigger jitter.gif!
