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.

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

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.

356

361
4083   debug daq, only top preshower and top shower on, TS4 only, PS4=1, threshold=85mV

Result(conclusion): cable connections are all good.

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)

   FADC is coming right after the summing. All four ShowerSum signals used in vmeDSC are from the extra FIFO.

   This FIFO will have ~10ns delay, which will match to CerSum better.

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.
683
FADC250_ALLCH_DELAY 80 80 80 80 80 80 80 0 80 80 80 80 80 80 80 80  
684
685

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.
