208 | 4022 disabled pulse trigger. only TS1,TS2,TS3,TS6 enabled, PS3=PS6=15, PS1=5,PS2=12, 1.8uA beam. 5.7KHz |
||
209 | |||
210 | Conclusion: on He3 target, PS1=5 will have 1.8kHz/uA for TS#1, PS2=12 will have 1.4kHz/uA for TS#2. |
||
211 | We still need to determine PS for PS4 and PS5. |
||
212 | After analyze run 4022, I found that for PS3=15, TS#3 has 28Hz/2uA. For PS6=15, TS#6 has 8Hz/2uA. Scaling PS from |
||
213 | 15 to 10, we got TS#3 rate as 450Hz/uA and TS#6 rate 130Hz/uA. |

308 | |||
309 | Mistakes for runs from 3972 to 4066 |
||
310 | 1. The vmeDSC has positive pulse output if one follows the +|- label. NIM logic board expects |
||
311 | negative pulse inputs. Therefore our TS#1,TS#2 and TS#3 in run 3972-4066 are not what we designed. |
||
312 | TS#1 and TS#2 are logical "OR". TS#3 is complicated to express. |
||
313 | |||
314 | Mistakes for runs between 4023 and 4066: |
||
315 | 1. TS#4 is actually triggered by SC_B due to cable wrongly shift by 1 pin. |
||
316 | On Jan 20 I tried to move TS#4(vmeDSC_ch12) and TS#5(vmeDSC_ch11) to vmeDSC_ch14 and vmeDSC_ch15. |
||
317 | But they are actually shifted by one pin location, which are vmeDSC_ch15 and vmeDSC_ch16. |
||
318 | Due to this mistake, trigger-bit 4 (0x1000) is actually triggered by SC_B (the SC behind shower), |
||
319 | Runs 4023-4066 are affected. |
||
320 | |||
321 | ========================================================= |
||
322 | 20230124 |
||
323 | Fixed ECL cable invertly connection problem, FADC TrigOut is connected to vmeDSC_ch16, then connecting to TS#6 |
||
324 | Verified TS#1-5 using function generator, still need to verify TS#6 from data |
||
325 | |||
326 | 4067 all TS1-6, no PS, pulse trigger, no beam |
||
327 | 4068 all TS1-6, no PS, pulse trigger, no beam |
||
328 | 4069 all TS1-6, no PS, cosmic trigger trigger, no beam |
||
329 | ==cosmic trigger threshold== |
||
330 | Threshold is applied to the height of the waveform: |
||
331 | TS1: CerSum(150mv or 307 adc unit) & ShowerSum(30mv or 61 adc unit); |
||
332 | TS2: SC_D(20mv or 164 adc unit) & ShowerSum(30mv or 61 adc unit) & SC_B(15mv or 123 adc unit). |
||
333 | TS3: 2 out of these 3 inputs: CerSum(150mv or 307 adc unit), ShowerSum(30mv or 61 adc unit), SC_D(20mv or 164 adc unit); |
||
334 | TS4: ShowerSum(50mv or 102 adc unit). |
||
335 | TS5: SC_B(20mv or 164 adc unit). |
||
336 | TS6: CerA#,CerB#,CerC#,CerD#(15mv or 31 adc unit) for each Cherenkov individual input |
||
337 | |||
338 | ========================================================= |
||
339 | |||
340 | to do: |
||
341 | look into run 4055 for Shower_R and SC_A |
||
342 | |||
343 | Raise TS4 threshold to 700mV and take some runs. |
||
344 | 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). |
||
345 | Need dedicated runs for each of TS4,5,1,2,3, in that order, and ideally also one run with all triggers on. |
||
346 | |||

||
352 | 4076 40uA beam on Carbon target, TS#3 only, PS3=10, all HVs are on. threshold: CerSum(200mV),SC_D(20mV),ShowerSum(50mV), daq rate is 5.5kHz. |

||
355 | 4079 40uA beam on Carbon target, TS#6 only, PS6=5, all HVs are on. threshold: CerSum(200mV), daq rate is 0Hz. MaPMTs are fully saturated. |
||
356 | 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. |
||

||
359 | 4081 debug daq, only left preshower and left shower on, TS4 only, PS4=1, threshold=85mV |

360 | 4082 debug daq, only right preshower and right shower on, TS4 only, PS4=1, threshold=85mV |
||
361 | 4083 debug daq, only top preshower and top shower on, TS4 only, PS4=1, threshold=85mV |
||
362 | |||
363 | Result(conclusion): cable connections are all good. |
||
364 | |||
365 | ========================================================= |
||
366 | |||
367 | A) What type of input pulse TI expects? |
||
368 | The TI we are using expects a positive differential pulse (meaning positive pulse on the + pin, |
||
369 | and simultaneously a negative pulse on the - pin). |
||
370 | The output of most level translator used in JLab can connect directly to TI, but not any logic unit output. |
||
371 | Its manual can be found here: |
||
372 | https://coda.jlab.org/drupal/system/files/pdfs/HardwareManual/TI/TI.pdf |
||
373 | |||
374 | B) can we tell readout to read FADC waveform even though it can not pass the given threshold? |
||
375 | |||
376 | JLab FADC250 can force all channels to be readout even with a threshold still specified. |
||
377 | The flag/mask, FADC250_TET_IGNORE_MASK, tells the readout whether or not to use the threshold (but the trigger will). |
||
378 | For example: |
||
379 | FADC250_TET_IGNORE_MASK 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 |
||
380 | |||
381 | to do: |
||
382 | 1) Addjust the following thresholds |
||
383 | Trig5: SC_B 10mV |
||
384 | Trig4: addjust threshold to get 3-4 kHz rate when PS4=0; |
||
385 | Trig2: SC_B 10mV, SC_D 10mV, ShowerSum 10mV |
||
386 | |||
387 | **Trig1 and Trag3 not mentioned in the meeting, should I change ShowerSum for these 2??? |
||
388 | |||
389 | 2)take dedicated runs for each trigger type in this order : TS4, TS5, TS1, TS2, TS3, TS6 |
||
390 | It will take about 45s-60s to change TS configuration. |
||
391 | Each run will take about 300k to 400k triggers for 60s of beam time. |
||
392 | in total 12 minutes. |
||
393 | |||
394 | 3)take one run with all triggers on. (2 minutes including TS configuration changing time) |

536 | 1. HV channel of 2nd GEM (from upstream to downstream) switched from Board A.1 to A.5. |
||
537 | A.1 is not stable, sometimes it will not work, sometime do. |
||
538 | 2. Reconnected SC_A signal cable |
||
539 | 3. Reduced the delay cable length of SC_B by 5 feet, |
||
540 | 4. We need to have 5 copies of ShowerSum signal. One go to FADC, four go to vmeDSC. |
||
541 | Therefore we need to have an extra FIFO after summing up 3 shower blocks. The copy goes to |
||
542 | FADC is coming right after the summing. All four ShowerSum signals used in vmeDSC are from the extra FIFO. |
||
543 | This FIFO will have ~10ns delay, which will match to CerSum better. |
||
544 | (In the past vmeDSC ch03,ch04,ch05 are all come from summing unit, FADC and vmeDSC ch14 are from the extra FIFO.) |

668 | |||
669 | conclusion: |
||
670 | 1) TS5: SC_B signal is 200ns earlier than TS5 |
||
671 | 2) TS4: Shower_L,Shower_R,Shower_T are 200ns earlier than TS4, ShowerSum is 6ns later than Shower_L |
||
672 | 3) TS1: only one peak, but showers have a wide range of 12~14 windows |
||
673 | 4) TS2: only one peak, but most detectors have a wide range of 14-16 windows |
||
674 | 5) SC_D, SC_B, CerSum have 44ns,38ns,44ns cable delay. SC_B is 6ns later than SC_D before delay. |
||
675 | After these delay, SC_B is 16ns later than ShowerSum, CerSum is 4ns later than ShowerSum. |
||
676 | We need to reduce the delay cable length for SC_B, SC_D and CerSum. |
||
677 | 6) TS6 is 352ns (or 88 windows) behind its input signals |
||
678 | |||
679 | Trigger signal at Slot7_ch07 is 9 windows eariler than the trigger signal at slot8_ch15. Because Slot7_ch07 signal |
||
680 | is only 1 window later than that of Slot8_ch15, we should set FADC250_W_OFFSET 10 windows 40ns eariler in order to |
||
681 | match these 2 slots in timing. Therefore I changed slot7 from "FADC250_W_OFFSET 1060" to "FADC250_W_OFFSET 1100". |
||
682 | I also changed slot7 FADC250_ALLCH_DELAY from 160ns to 80ns. |

719 | |||
720 | How to determine TS6 latency: |
||
721 | basic knowledge: |
||
722 | A) TS6 (FADC trigger) is ~88 windows behind FADC input signal (viewed in DiagGui). |
||
723 | B) TS4(NIM trigger) is about 49 windows behind the input signal of logic unit (viewed in data). |
||
724 | |||
725 | 1) Use TS4 (NIM trigger, trigger by slot8_ch14), plug the trigger signal(L1A) into FADC slot7 and slot8. |
||
726 | Modify FADC250_W_OFFSET and FADC250_ALLCH_DELAY of FADC config file such that the peaks of |
||
727 | these 2 signals stay at the same time in slot7 and slot8. The following is my current setting. |
||
728 | Trigger signals have ZERO delay. |
||
729 | |||
730 | slot7: FADC250_W_OFFSET 1100 |
||
731 | slot7: FADC250_ALLCH_DELAY 80 80 80 80 80 80 80 0 80 80 80 80 80 80 80 80 |
||
732 | slot8: FADC250_W_OFFSET 1060 |
||
733 | slot8: FADC250_ALLCH_DELAY 40 80 40 40 80 80 80 40 40 40 40 40 40 40 40 0 |
||
734 | Here is the peak location of each channel. |
||
735 | 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 }; |
||
736 | 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 }; |
||
737 | Note that the trigger signal of slot7_ch07 is 6ns late than that of slot8_ch14 because it gord thrught an extra FIFO. |
||
738 | |||
739 | 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 |
||
740 | delay TS4 by 137.5 - 77.5 = 60 windows. In my case, I change the readout list, delay TS4 by 54 windows. |
||
741 | We fisrtly change FADC250_W_OFFSET to view the peak location of these 2 trigger signals. |
||
742 | To keep slot7_ch07 at 78.5, slot7_W_offset should be 1100 - 60x4 = 860. |
||
743 | To keep slot8_ch15 at 77.5, slot8_W_offset should be 1060 - 60x4 = 820. |
||
744 | Since FADC trigger is 88 windows later than its inputs, it is impossible to view inputs and trigger within a 400ns windows. |
||
745 | Therefore do not bother to change slot7 delay. But we can add 60 windows (240ns) delay to slot8 such that the peaks of all |
||
746 | channels stay the same location. |
||
747 | |||
748 | slot7: FADC250_W_OFFSET 860 |
||
749 | slot7: FADC250_ALLCH_DELAY 80 80 80 80 80 80 80 0 80 80 80 80 80 80 80 80 |
||
750 | slot8: FADC250_W_OFFSET 820 |
||
751 | slot8: FADC250_ALLCH_DELAY 256 296 256 256 296 296 296 256 256 256 256 256 256 256 256 0 |
||
752 | |||
753 | Take a run using TS6 trigger with the above changes to determine the peak location for 2 trigger signals. |
