Noise scan
Using the information from the threshold scan it is possible to give an estimation of the noise, expressed both in occupancy (%) and in rate (Hz).
The following file contains the detailed information for all the investigated FEBs. FEB2 data are missing since it is not properly calibrated.
Some information on the variable used: - noise: number of hits with charge > 2 fC and in a time window of -100 < t < 200 ns around the trigger time - total: number of events in each run - DAQ time: 300 ns time window times the number of events. It is the total time considered. - hit_event: ratio between noise and total - occupancy: hit_event divided by the number of channels (in the runs 63-87, 124 channels per each FEB) multiplied by 100. - total noise: noise divided DAQ time - noise rate: hit_event divided by DAQ time. It is the rate of noise per strip.
