We fiddled around with EXL trying to get a reasonnable 60Co spectrum.
We moved the source to the windows flange, so it is now facing the EXL detector with minimal matters inbetween, although rather far away (around 1m).
We set change the hardware gain on the second module, so the last two channels have the same hardware gain than the rest of the detector. This is an hardware gain of 30.
We set the software gain to 0 overall.
We set the software threshold to 15.
A rought estimate made this a 7 MeV range with a 300 keV threshold.
We are taking data (run 15) to check that. |
