S1 and S2m time difference and corrected time plots for run 2512 after initial time offset calibration:

Corr times 2512.gif
Beta 2512.gif


The left figure shows that the time differences are fairly well calibrated, but the corrected times show some shifts for a few paddles in S1 and S2m. The beta spectrum shows some discontinuities that I thought might be related to the time offset shifts. I will present more on this in the discussion below. The beta spectrum has a long tail for beta greater than 1, and the beta resolution is about 0.14.

For the second iteration, I decided to look at a recent production run: 3789.
