DAQ commands

Source CODA and ROOT

source ~/CODA/2.6.2/setup
source /home/daq/src/root/root-5.34.00/bin/thisroot.csh

Run the bash script titled 'jeff', which takes the run number as an argument. This script will automatically convert the .dat file to a .root file and then open it in root. The script: File:Jeff.txt.

bash jeff 4716

The first index of evt.TDC1190 is the hit #. The second index increases consecutively with TDC channel number, but the index starts from 1, while the TDC channels start at 0.

Common ROOT plot commands for copy-past:

First hit minus second hit:

 R1DC->Draw("(evt.TDC1190[2][1]-evt.TDC1190[1][1])")

PMT difference:

R1DC->Draw("(evt.TDC1190[1][2]-evt.TDC1190[1][3])/10","evt.TDC1190[1][2]!=0 && evt.TDC1190[1][3]!=0 && evt.TDC1190[1][1]")

PMT Sum, where evt.TDC1190[1][1] is the trigger:

R1DC->Draw("(evt.TDC1190[1][3]/10+evt.TDC1190[1][2]/10)/2-evt.TDC1190[1][1]/10>>PMTSum(1000,-500,500)","evt.TDC1190[1][2]!=0 && evt.TDC1190[1][3]!=0 && evt.TDC1190[1][1]!=0")

TDC Calibration

The data was collected by taking the channel difference between two pulses with a delay of 500,600,700, and 800 ns.
