NaI detector setup

Creating ROOT data files

source ~/CODA/setup

/home/daq/CODA/CODAreader/ROOT_V5.34/PAA/evio2nt -fr6815.dat > /dev/null

Analyzing ROOT data file

root -l r8735.root

to draw a histogram for Peak ADC channel 4


To scale the histogram using an energy calibration of 0.45 keV/channel


To save thehistogram under the name Cs137


To normalize the histogram by a run time of 2600 seconds



run 6816 background (~300Hz) 1/47 = 0.021277

run 6817 signal (~600 Hz) 1/75 =0.013333
