(run4015) ------------------------------------------------------------------------ Mistakes for runs from 3972 to 4066 1. The vmeDSC has positive pulse output if one follows the +|- label. NIM logic board expects negative pulse inputs. Therefore our TS#1,TS#2 and TS#3 in run 3972-4066 are not what we designed. TS#1 and TS#2 are logical "OR". TS#3 is complicated to express. Mistakes for runs between 4023 and 4066: 1. TS#4 is actually triggered by SC_B due to cable wrongly shift by 1 pin. On Jan 20 I tried to move TS#4(vmeDSC_ch12) and TS#5(vmeDSC_ch11) to vmeDSC_ch14 and vmeDSC_ch15. But they are actually shifted by one pin location, which are vmeDSC_ch15 and vmeDSC_ch16. Due to this mistake, trigger-bit 4 (0x1000) is actually triggered by SC_B (the SC behind shower), Runs 4023-4066 are affected. ========================================================= 20230124 Fixed ECL cable invertly connection problem, FADC TrigOut is connected to vmeDSC_ch16, then connecting to TS#6 Verified TS#1-5 using function generator, still need to verify TS#6 from data 4067 all TS1-6, no PS, pulse trigger, no beam 4068 all TS1-6, no PS, pulse trigger, no beam 4069 all TS1-6, no PS, cosmic trigger trigger, no beam ==cosmic trigger threshold== Threshold is applied to the height of the waveform: TS1: CerSum(150mv or 307 adc unit) & ShowerSum(30mv or 61 adc unit); TS2: SC_D(20mv or 164 adc unit) & ShowerSum(30mv or 61 adc unit) & SC_B(15mv or 123 adc unit).

For TS4-only run, please adjust PS to keep rate at 3kHz. (If PS is too high, raise the threshold to 800mV or 900mV or 1V). Need dedicated runs for each of TS4,5,1,2,3, in that order, and ideally also one run with all triggers on. 4071 40uA beam on Carbon target, TS#4 only, PS=0, only Shower HVs are on. ShowerSum threshold is 85mV, daq rate is 4.5kHz. 4072 40uA beam on Carbon target, TS#5 only, PS=0, only SC_B HV is on.

MaPMTs are fully saturated. 4080 40uA beam on Carbon target, TS#5 only, PS=8, only SC_B HV is on. SC_B threshold is 30mV, daq rate is 6.8kHz. ==I doubt the signal cable of left and right shower are swapped== 4081 debug daq, only left preshower and left shower on, TS4 only, PS4=1, threshold=85mV 4082 debug daq, only right preshower and right shower on, TS4 only, PS4=1, threshold=85mV 4083 debug daq, only top preshower and top shower on, TS4 only, PS4=1, threshold=85mV Result(conclusion): cable connections are all good. ========================================================= A) What type of input pulse TI expects? The TI we are using expects a positive differential pulse (meaning positive pulse on the + pin, and simultaneously a negative pulse on the - pin). The output of most level translator used in JLab can connect directly to TI, but not any logic unit output. Its manual can be found here: https://coda.jlab.org/drupal/system/files/pdfs/HardwareManual/TI/TI.pdf B) can we tell readout to read FADC waveform even though it can not pass the given threshold? JLab FADC250 can force all channels to be readout even with a threshold still specified. The flag/mask, FADC250_TET_IGNORE_MASK, tells the readout whether or not to use the threshold (but the trigger will). For example: FADC250_TET_IGNORE_MASK 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 to do: 1) Addjust the following thresholds Trig5: SC_B 10mV Trig4: addjust threshold to get 3-4 kHz rate when PS4=0; Trig2: SC_B 10mV, SC_D 10mV, ShowerSum 10mV **Trig1 and Trag3 not mentioned in the meeting, should I change ShowerSum for these 2??? 2)take dedicated runs for each trigger type in this order : TS4, TS5, TS1, TS2, TS3, TS6 It will take about 45s-60s to change TS configuration. Each run will take about 300k to 400k triggers for 60s of beam time. in total 12 minutes. 3)take one run with all triggers on.

SC_B is 6ns later than SC_D before delay. After these delay, SC_B is 16ns later than ShowerSum, CerSum is 4ns later than ShowerSum.

B) TS4(NIM trigger) is about 49 windows behind the input signal of logic unit (viewed in data). 1) Use TS4 (NIM trigger, trigger by slot8_ch14), plug the trigger signal(L1A) into FADC slot7 and slot8. Modify FADC250_W_OFFSET and FADC250_ALLCH_DELAY of FADC config file such that the peaks of these 2 signals stay at the same time in slot7 and slot8. The following is my current setting. Trigger signals have ZERO delay. slot7: FADC250_W_OFFSET 1100 slot7: FADC250_ALLCH_DELAY 80 80 80 80 80 80 80 0 80 80 80 80 80 80 80 80 slot8: FADC250_W_OFFSET 1060 slot8: FADC250_ALLCH_DELAY 40 80 40 40 80 80 80 40 40 40 40 40 40 40 40 0 Here is the peak location of each channel. double kSlot7PeakPos_4[16] = { 44.5, 43.5, 44.5, 44.5, 43.5, 43.5, 43.5, 78.5, 43.5, 43.5, 43.5, 43.5, 43.5, 43.5, 43.5, 43.5 }; double kSlot8PeakPos_4[16] = { 40.5, 35.5, 41.5, 39.5, 38.5, 37.5, 31.5, 35.5, 35.5, 36.5, 37.5, 37.5, 37.5, 37.5, 38.5, 77.5 }; Note that the trigger signal of slot7_ch07 is 6ns late than that of slot8_ch14 because it gord thrught an extra FIFO. 2) From the above peak location, we can see that TS6_peak = 43.5 + 94 = 137.5 (windows). To align TS4 to TS6, we have to delay TS4 by 137.5 - 77.5 = 60 windows. In my case, I change the readout list, delay TS4 by 54 windows. We fisrtly change FADC250_W_OFFSET to view the peak location of these 2 trigger signals. To keep slot7_ch07 at 78.5, slot7_W_offset should be 1100 - 60x4 = 860. To keep slot8_ch15 at 77.5, slot8_W_offset should be 1060 - 60x4 = 820. Since FADC trigger is 88 windows later than its inputs, it is impossible to view inputs and trigger within a 400ns windows. Therefore do not bother to change slot7 delay. But we can add 60 windows (240ns) delay to slot8 such that the peaks of all channels stay the same location. slot7: FADC250_W_OFFSET 860 slot7: FADC250_ALLCH_DELAY 80 80 80 80 80 80 80 0 80 80 80 80 80 80 80 80 slot8: FADC250_W_OFFSET 820 slot8: FADC250_ALLCH_DELAY 256 296 256 256 296 296 296 256 256 256 256 256 256 256 256 0 Take a run using TS6 trigger with the above changes to determine the peak location for 2 trigger signals. ======================================================================== 20230219 run list All HVs are on without GEM.
