Lamiaa,
<div class=""><br class="">
</div>
<div class="">For the most part things are in decent shape carrying over the calibration constants from RG-C in November 2022</div>
<div class="">and projecting them into the RG-D run range. What is see is very much what I expected. There are some things to</div>
<div class="">note from my perspective looking at things quickly:</div>
<div class=""><br class="">
</div>
<div class="">1) DC - residual means relative constant vs. run number but shifts up to 300 microns. sigmas are already in spec.</div>
<div class="">2) FTOF - energy calibration needs adjustment. panel-1b timing within +/-40 ps of nominal. Resolution out of spec</div>
<div class="">due to poor energy calibration (which affects time walk correction).</div>
<div class="">3) r18360-18369 - S2 problem needs investigation</div>
<div class="">4) CTOF - timing is a mess. Is this because of event selection not associated with the electron trigger?</div>
<div class="">5) EC- empty plots for r18432-18474. Why? Otherwise sampling fraction is reasonable. Timing shifted by 250 ps</div>
<div class="">before r18401.</div>
<div class="">6) HTCC - gain and timing pretty good. However, S2 is missing in a lot of the plots.</div>
<div class="">7) CND - timing within 100 ps with a slow worsening drift vs. run number.</div>
<div class=""><br class="">
</div>
<div class="">Seems S2 is a significant problem across a sizeable fraction of the run range. We can talk about this tomorrow at</div>
<div class="">CALCOM.</div>
<div class=""><br class="">
</div>
<div class="">Regards,</div>
<div class="">Daniel</div>
