<p>Over the past 24 hours we collected ~3.43B total triggers on the He4 target with 200nA beam. Starting from run_num 111140 one of FCal fADC is broken. The beam was pretty stabile till ~16:37 there was some issues with RF 1L10 HV. At around 19:55 beam came back, and we continued collecting data. Then at 0:25 got call from CH, regarding DAQ rate drops dramatically from ~50kHz to ~0kHz, contacted to Sergey Furletov, and after some investigations, Sergey advised to reboot the rocTOF2, after power cycling it the rate increased to ~12kHz, but still way bellow the nominal rates (50kHz), it turns out one of FCal outer ring fADC is broken (<a href="https://logbooks.jlab.org/entry/4065801">https://logbooks.jlab.org/entry/4065801</a>), which is causing the rate drop, Sergey excluded it from FCal trigger, which brought back the DAQ rate to nominal value.<br />
During this time tried to contact to expert, to schedule a rapid access to hall to replace the broken fADC. NO LUCK to reach to expert.<br />
Will continue running with this condition until the fADC will be replaced.<br />
The other issue was related to gluon-03 machine, it was unresponsive from CH, but with remote connection it was OK, at around 9:38am after consulting with Sergey, rebooted the machine, now it is running as normal.</p>
<p>!!Stay Tuned!! </p>
<p>=Saturday, October 22=<br />
=== Past 24 hours ===<br />
* past 24 hours we collected ~3.43B total triggers on the He4 target with 200nA beam.<br />
* Starting from run_num 111140 one of FCal fADC is broken<br />
* Beam was OFF from 16:37 till 19:58 issues with RF 1L10 HV<br />
* After Beam is back continued taking data at 200nA FULL target<br />
* ~00:15 DAQ rate dropped to 0kHz, Contacted to Sergey, 1st power cycled rocTOF2, which brings trigger rate to 12.5kHz, but still way far from nominal 50kHz<br />
* It turns out one of FCAL outer ring fADC is broken (trying to reach expert to replace it), will continue running with this condition until it's been replaced</p>
