+ | * 3/25/2015 | ||
+ | ** Sean and Glen examined all of the signals from detectors 1 through 6 | ||
+ | ** We used the signal from the LEMO cables that go directly into the discriminator | ||
+ | ** We also used the scope's Acquire->Average option and set the average to 512; This allowed for a more reliable comparison between signals | ||
+ | *** Note that the threshold can be adjusted and that the average will be biased toward smaller pulse heights if there is a lot of noise | ||
+ | ** Found an RG-62 cable connected between the bottom PMT of Det 3 and the patch panel A10 | ||
+ | *** Replaced with RG-58 cable | ||
+ | ** A10 cable also found to be RG-58 from the experiment room to the counting room; Signal on 3B was degraded in the control room | ||
+ | *** Changed to A19 (RG-223 the whole length) and the signal looked similar to the others | ||
+ | ** Found that detector 5 top and bottom both were small and have the ~12 ns ringing | ||
+ | *** Increased voltage to 1500V | ||
+ | *** The non-extending gates from the discriminator will help with this | ||
+ | *** Recommend a gate width of 20 to 25 ns from the discriminator to eliminate double pulsing from ringing on Det 5 | ||
+ | *** Should not matter for other detectors | ||
+ | *** Will also not affect high energy neutrons since 6 MeV neutrons are 30 ns ToF at 1 meter | ||
+ | ** When testing was complete, verified that all cables are associated with the appropriate detector | ||
+ | ** Top/Bottom, Upstream/Downstream should not have been reversed for any detectors in the process but that has not been confirmed; this should be correctable in software | ||

Signal Processing
Discriminator
CAEN N841
The pulse forming stage of the discriminator produces an output pulse whose width is adjustable in a range from 5 ns to 40 ns. Each channel can work both in Updating and Non-Updating mode according to on-board jumpers position. The discriminator thresholds are individually settable in a range from -1 mV to -255 mV (1 mV step), via an 8-bit DAC. The minimum detectable signal is -5 mV. The back panel houses VETO and TEST inputs, the OR output and the Current Sum output, which generates a current proportional to the input multiplicity, i. e. to the number of channels over threshold, at a rate of -1.0 mA per hit (-50 mV per hit into a 50 Ohm load) ±20%.

Wiring Work
- 3/25/2015
- Sean and Glen examined all of the signals from detectors 1 through 6
- We used the signal from the LEMO cables that go directly into the discriminator
- We also used the scope's Acquire->Average option and set the average to 512; This allowed for a more reliable comparison between signals
- Note that the threshold can be adjusted and that the average will be biased toward smaller pulse heights if there is a lot of noise
- Found an RG-62 cable connected between the bottom PMT of Det 3 and the patch panel A10
- Replaced with RG-58 cable
- A10 cable also found to be RG-58 from the experiment room to the counting room; Signal on 3B was degraded in the control room
- Changed to A19 (RG-223 the whole length) and the signal looked similar to the others
- Found that detector 5 top and bottom both were small and have the ~12 ns ringing
- Increased voltage to 1500V
- The non-extending gates from the discriminator will help with this
- Recommend a gate width of 20 to 25 ns from the discriminator to eliminate double pulsing from ringing on Det 5
- Should not matter for other detectors
- Will also not affect high energy neutrons since 6 MeV neutrons are 30 ns ToF at 1 meter
- When testing was complete, verified that all cables are associated with the appropriate detector
- Top/Bottom, Upstream/Downstream should not have been reversed for any detectors in the process but that has not been confirmed; this should be correctable in software

Beam spot flags
Below is a picture of the three "flags" that you can use to the beam spot size using a phosphorus screen.
Software
here is the raw C code for "evio2nt", which is the program we use to create a ROOT tree from a .dat file.
Ntuple maker
To make the Tree containing the TDC, QDC, and PDC data run the following command
source ~/CODA/setup
/home/daq/CODA/CODAreader/ROOT_V5.30/v775v792v785/evio2nt -fr8735.dat >/dev/null
rename the output file to a root file
mv r8735 r8735.root
root -l r8735.root
to draw a histogram for TDC channel 16
DAQ->Draw("evt.TDC[17]>>(4096,0,4096)");
for the multihit TDC data taken with daq2
CODA/CODAreader/ROOT_V5.30/R1DC/evio2nt -fr4516.dat > /dev/null
R1DC->Draw("(evt.TDC1190[1][3])");
R1DC->Draw("(evt.TDC1190[1][6]-evt.TDC1190[2][6])/10>>(4096,-4096,4096)");
On 4/9/2015 the above should be 4000 channel = 400 ns
Analyzing MultiHit TDC runs
setup ROOT on daq 2
source ~/src/root/root-5.34.00/bin/thisroot.csh
IN run 4481 the time difference between the two fake stop pulses seems to be 205.8 ns
R1DC->Draw("(evt.TDC1190[2][6]-evt.TDC1190[1][6])/10");
The relative time of a hit in detector 1 top is given relative to the first fake stop hit using the command
R1DC->Draw("(evt.TDC1190[1][8]-evt.TDC1190[1][6])/10");
Doing the same plot above but this time sending it to a histogram with 1 ns bins
R1DC->Draw("(evt.TDC1190[1][8]-evt.TDC1190[1][6])/10 >> (1000,0,1000)")
