<p> Energy calibration for S2-2 was done using the pulser data (set 6 of the pulser runs) to calculate the offsets and alpha run R186 to calculate the gains and constant. For S2-1 pulser walkthrough 6 was also used to calculate the offsets and the gains calculated using run 31 which is 21Ne beam scattering from Au/C target. The constants were then calculated by fitting a least squares fit to the alpha peaks from run 186 and the gold scattering peak from run 31 energy vs peak position plot.</p>
<p style="margin-bottom: 0cm">TDCs were calibrated with different sources for each detector. For S2-1 the offsets were calculated using the TDC spectra for the 21Ne on Au/C (Run 31) data. For S2-2 the run 23 was used which is a pulser run.</p>
<p style="margin-bottom: 0cm">Currently applying equal energy and coincidence cuts to the data and plotting using Monte Carlo to compare to what I am seeing in the data. Plotting things such as Energy in S2-1 vs Energy in S2-2, back strip in S2-1 vs back strip in s2-2, energy sum.</p> |
