9.360 Threshold + 9.360 width + 4.680 temp. Front-End Board Data I.N.F.N. Naples Barrel FEB is equipped with 2 front-end chips (8 strips each) and 1 temperature sensor. For each chip there are: 2 threshold value (hardware defaults of 200 mV); 2 width values (hardware defaults of 100 ns); 1 temperature value. How many operations/bytes do we need to read/write this parameters ?? Read width/thresh.  2 write + 1 read  5 bytes Read temperature  2 write + 1 read  5 bytes Write width/thresh.  3 write  6 bytes TOTAL number of FEB parameters are 9.360 Threshold + 9.360 width + 4.680 temp. 21/09/2018 Pigi Paolucci, I.N.F.N. of Naples

RPC Barrel configuration Data I.N.F.N. Naples Barrel RPC detector is equipped with 480 HV channels and with 780 LV channels. To configure the detector we need to set: Vset, Vmax, Iset, Imax, Trip, Rup, Rdown, On/Off. HV & LV configuration requires about 1260 ch * 8 par. = 10.080 par * 2 bytes = 20 KB FEB configuration requires about 3.4 Kbytes per Link Board corresponding to 2 MB. 21/09/2018 Pigi Paolucci, I.N.F.N. of Naples

RPC configuration states I.N.F.N. Naples The RPC detector will have “at least” 3 different configuration states (data, calibration, “injection/safe”); Plateau calibration needs from 5 to 7 runs with different configuration parameters (HV set-points) when the others muon systems are working/triggering in “normal mode”. Noise calibration runs (?) needs few runs with different FEB thresholds but fixed HV set-points. 21/09/2018 Pigi Paolucci, I.N.F.N. of Naples
