4286 - 4293 GEM cosmic
20230221 Work done in the Hall or the counting house:
1) Moved bunker to new location, push detector stand & table to 18deg. Align the table to the target with laser pen.
2) GEM detectors:
A) Use NEW LV cable which can connect to the LV board in the MPOD crate
B) Install 1x1 foot poly shileding
C) Align the trigger latency for all 4 triggers within 20ns
3) SC, PreShower and Shower detectors:
A) Change triggers TS2 as "SC_D & SC_B", TS3 as "SC_A & SC_D", remove TS5
B) Connect SC_A,SC_B,SC_C and SC_D to x10 multiplier
C) Align trigger latency between TS1,TS2,TS3 and TS4 within 4ns using function generator
D) Increase LASPD HVs by 10% from (T,B)=(800,900) to (880,990)
E) Preshower averaged pulse height is ~40ADC, increase their HVs(L,R,T) from (1470,1740,1680) to (1515,1800,1730),
which is determined from the cosmic and gain matched on Jan 11th.
4) Do pedestal run for FADC without HVs. FADC configuration file is updated to match the above changes and the new pedestal.

===Run plan===
start with TS4, PS=10, determine the prescale factor by scan the threshold,
then take data for each trigger bit to determine peak time
TS4, Threshold=40mV, set proper PS4 such that rate=3kHz to take one run
TS3, Threshold 50mV & 50mV, determine PS3 then take one run
TS2, Threshold 50mV & 50mV, determine PS2 then take one run
TS1, Threshold 50mV & 50mV, determine PS1 then take one run
Set proper PS1,PS2,PS3 and PS4, take 2 runs with all triggers

Threshold Guidence:
1) ShowerSum: MIP is at ~470 ADC, which is 40MeV. Shower sampling is 20%. Therefore 1 GeV electron will have ~2350 ADC in integral.
The averaged Integral/Height for ShowerSum is 8.2, Note that 1ADC=0.488mV, therefore the threshold corresponding to 2350 ADC
integral is 0.488*2350/8.2 = 140 mV.
Sugggested threshold for ShowerSum:
To cut off 1 GeV electron: 140mV
To cut off 500MeV electron: 70mV
To keep low energy photon background: 10mV
140mV can only cut off 50% 1 GeV electrons.
To Cut of 99.7% of 1 GeV electrons (3-sigma), we need to apply threshold: 0.488*2350/(8.23-3*0.7345) = 190mV
To include 99.7% of 1GeV electrons: 0.488*2350/(8.23+3*0.7345) = 110mV
To include 95% of 1GeV electrons: 0.488*2350/(8.23+2*0.7345) = 118mV ---> rounded to 120mV
2) TS2: Half MIP: SC_B=45mV, SC_D=35mV (By Jx: SC_B(1650V)=57mV, SC_D(1150V)=34mV)
3) TS3: Half MIP: SC_A=35mV, SC_D=35mV (By Jx: SC_A(1550V)=31mV, SC_D(1150V)=34mV)

Work done on 20230301
1. Signal cable for SC_C(253) and CerB3 (285) were swapped in the patch panel. They look similar to each other
since the labels are faded out. After swapping them back both look good. CerB3 is now connected to FADC Slot7 ch07,
but it is not included in CerSum.
2. Change all Cherenkov FADC range from 2.0V to 1.0V, including the CerSum at FADC slot8 ch03. By doing this, 1ADC=0.244mV,
Cherenkov signal height will be doubled therefore in the new data it will not be affected as much as before by the peak
finding threshold cut (default 20 adc).
3. Change PreShSum (Slot8 ch13) range from 2.0V to 0.5V so it matches to PreShower individual detectors. By doing this,
software sum should match to the hardware sum.
4. Change latency of each trigger bit. Align TS1, TS2 and TS3 to TS4 within 4ns. All inputs after the vmeDSC are aligned within 4ns.

20230306 work done in the hall
1) Replaced GEM gas bottle
2) Fixed HV VBound problem for GEM1
3) Checked all cables in the DAQ end to avoid possible loose connection. Reconnect CerC0. Add CerB3 back into CerSum.
Addjusted the FIFO output offsets for CerA, CerB, CerC and CerD to zero, but keep the offset of CerSum as +10mV.
In order to compesate this +10mV offset, its DAC value in FADC config file has been updated from 3330 to 3300.
4) Checked output offset for x10 amplifier that is used by SC_A, SC_B, SC_C and SC_D. It has +10mV~+14mV offsets.
However, the offset changes to ZERO if the input is a function generator. Is it a problem?)
5) Change latency for TS1-TS4, all are aligned to SC_B.
A) SC_A: add 8ns delay to SC_A before it goes into x10 amplifier
B) SC_D: add 4ns deday by replacing the 3ns cable which is connecting the X10 amplifier to the FIFO with a 7ns cable
C) SC_C: add 15ns delay to SC_C before it goes into x10 amplifier
D) Shower: delay Shower L|R|T by 4ns before they go into FIFO, replay the 2ns calbles which are connected FIFO to summing
module by the 8ns cables. Therefore ShowerSum get 10ns extra delay
E) CerSum: replace the 8ns delay cable (connected the CerSum to a FIFO) by a 15ns delay cable
F) all cables, except LASPD_t and LASPD_b, go into Slot8 have 8ns delay
6) Reconnect CerC0 at the detector end, this fix CerC0 problem!
