Update 07/31 (JB) : we now have the following FHE thresholds in MeV associated with the following BT configurations :
FHE(MeV) BT-#
500 17
750 18
1000 16
1500 19
2000 20
Please check the confluence DataTaking>Configuration page to see the details of these configurations. All the threshold files have been generated with the latest version of CalibGenCAL (v4r2p4?) and they passed the validation scripts.
So as soon as the beam is ready we can start study the FHE efficiency.
Update 07/31 (JB) : Trigger timing issue
A couple of nights ago we aligned the trigger primitives, so that now TKR, CAL_LO and CAL_HI triggers are aligned with the begginning of the trigger
window that is in our case always opened by the external trigger. We actually aligned the mean of the distribution with the 0 of the trigger
window so as to be sure that our TACK_DELAY values are correct. What we have seen in the first data (runs 820-821) is that the trigger primitive
timing distributions are quite wide, especially the CAL_HI one, so that after the alignment we only have half of the CAL_HI trigger request issued
within the trigger window. To be more efficient in the study of CAL_HI triggers, we could possibly adjust the ext_delay and tack_delay values so as to make sure that all the trigger primitive requests fits well inside the trigger window. This can be done quite easily adjusting the parameters in the BT configuration.
Please some CAL experts, tell me as soon as possible if that's usefull to do or not...
