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%.

Multi hit TDC timing

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)")
