Apparatus

Accelerator

Using the 44 Machine at 7 kW power and 44 meV incident electron energy to produce a bremsstrahlung spectrum with a mean energy of 15 MeV.

Target

General Target configurations, Selenium pellets are sandwiched between two Nickel foils

Target A

Target	Mass (g)
Ni Front	0.0994
Se Shot	1.7842
Ni Rear	0.0948

Target B

Target	Mass (g)
Ni Front	0.1075 g
Se Shot	1.1984 g
Ni Rear

Calibrations

On the daq1 machine in the subdirectory /data/IAC you can create ntuples using the list file created that has 3 column (ADCid, Chan, Time) and the ROOT program

.L List2Ntup.C
List2Ntup("filename")

Create a text file called temp.dat delimited with tabs where the channel number is in the first column, the photon energy in the second, and the sigma from the gaussian fit is in the third column

Then do

.L LinFit.C
MyLinFit(0,2)
