If a DAQ person is available or another GEM person knows how to properly manipulate the DAQ to accomplish this, I have no problem taking data like this. Also how long (i.e. how many events of cosmic data) would one want at each one of these DAQ configurations.</div><div><br></div><div>Zeke<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 9, 2021 at 5:16 PM Kondo Gnanvo <<a href="mailto:kagnanvo@jlab.org">kagnanvo@jlab.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal"><span style="font-size:11pt">Hi Zeke & Holly, <u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">For the cosmic run tonight with the GEMs, we would like to have a few specific runs to investigate the APV25 signal flip that we are observing with the data with beam so far.
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">So the plan is to have 3 dedicated runs:
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">1-) First run: standard run with online zero suppression (containing full non zero suppressed raw APV data every 100 events).
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">2-) Second run: run with no online zero suppression where we have access to all APV raw data<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">3-) third run: Zero suppressed event with 1 full raw APV data every 10 events<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">For this 3rd run, I don’t know if it is just a matter to set a variable in DAQ configuration file or if this would require any modification from Ben. If so, I guess we could skip it for tonight and discuss
it tomorrow at GEM meeting. <u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">Please let us know if this plan is clear and if you see any issue with that. If we have the data, then we could already have a first look at the APV raw data frames with Xinzhan script at the GEM meeting tomorrow
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">Best regards <u></u><u></u></span></p>
