- Trigger rate in Housekeeping packets
In ASW, trigger rate is calculated in the function below:
sid2->avgTrigAcc = 0; sid2->maxTrigAcc = 0; QLAccuDblBuffs_getAndResetTrigHK(&(sid2->avgTrigAcc), &(sid2->maxTrigAcc)); void QLAccuDblBuffs_getAndResetTrigHK(uint32_t* medTrig, uint32_t* maxTrig) { ASSERT(medTrig); ASSERT(maxTrig); *medTrig = 0; *maxTrig = 0; if (QLAccuDblBuffs_co.hk.trigCounter != 0) { *medTrig = utils_median(NUMBER_OF_GROUPS, NUMBER_OF_GROUPS, (uint32_t*)QLAccuDblBuffs_co.hk.trigSum) / QLAccuDblBuffs_co.hk.trigCounter; //find maximum for (uint32_t i = 0; i < NUMBER_OF_GROUPS; i++) if (QLAccuDblBuffs_co.hk.trigSum[i] > * maxTrig) *maxTrig = QLAccuDblBuffs_co.hk.trigSum[i]; *maxTrig /= QLAccuDblBuffs_co.hk.trigCounter; } //reset Volatile_memset(QLAccuDblBuffs_co.hk.trigSum, 0, sizeof(QLAccuDblBuffs_co.hk.trigSum)); QLAccuDblBuffs_co.hk.trigCounter = 0; }
MAX trigger rate of 16 detector pairs of the QL trigger accumulator ( 2 detector per group)
QL integration time = 4 s
Hence
trigger rate of each detector = HK2 max trigger rate / (4 * 2) = 350 /8=35
- Trigger rate in LC
4500 / (4 s *32) = 32 counts / detector
