<div>Hi Sean, </div>
<div>I thought it was discussed at the that we take cosmic data with the GEMs tonight </div>
<div>So i was assuming that the switching to no online zero suppression was straightforward </div>
<div><br>
</div>
<div>In any case, any data taken tonight, if any, will be useful to look at </div>
<div><br>

<div>Best Kondo </div>

<div dir="auto">We are not prepared to do all this work tonight. Also you would probably want at least 1 to 2 hours at each point that you suggest, so there is not enough time. We can work on it tomorrow though. </div>

<div>Hi Kondo,</div>
<div><br>
</div>
<div>I personally do not know how to really manipulate the DAQ to do these tasks. 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>

<p class="x_MsoNormal"><span style="font-size:11pt">Hi Zeke & Holly, <u></u><u></u></span></p>
<p class="x_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="x_MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="x_MsoNormal"><span style="font-size:11pt">So the plan is to have 3 dedicated runs:
<u></u><u></u></span></p>
<p class="x_MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="x_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="x_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="x_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="x_MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="x_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="x_MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="x_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="x_MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
