Are you allowed to take the first RTPC out of the lab? 
Would be good for some of you to have it and open it. Taking all the tools necessary to open it would be a plus of course. 

I forgot to bring some hardware home before confinement here, that's why I'm asking. 

Take care,

Hi All, 

this is the status and report of the BONuS experiment (Run Group F), Monday 23rd, 2020. 


    * Owl + Day VERY smooth and productive. Running 300nA @ 10.4 GeV 
    * 
        * just one RTPC 
    * During the MCC meeting, it was announced officially that the lab will move to MEDCON 6 implying the shutdown of all experiments starting on Tuesday at 8:00 AM 
    * 
        * it implies the prohibition to enter in the installations, however there will be a transient period where staff and users can prepare all the necessary detectors and devices to be safe during the shut down. Leader Group Marco and Physics Division Director Rolf sent instructions of how to proceed. 
    * Sebastian arrived at noon to proceed with calibration runs in this order 
    * 
        * He 
        * H2 
        * MT 
    * He notices that one of the Pre-mix gas bottle was practically empty, so he changed it before starts with the calibration runs 
    * 
        * OLD BOTTLE CO2 content was 19.8% 
        * NEW BOTTLE CO2 content is 21% 
    * During the change from He to H2, we run a Moeller Measurement 
    * 
        * one RTPC ramping down due to not bypassing pressure interlocks 
    * Calibration runs and D2 filling target ~18:20 
    * 
        * one RTPC trip during production. 
        * Sector 2 trigger gone, solved by Serguey 
    * Eric noticed that the event display is showing less occupancy pads and asked to compare the RTPC currents. 
    * 
        * [ https://logbooks.jlab.org/entry/3808742 | https://logbooks.jlab.org/entry/3808742 ] 
        * [ https://logbooks.jlab.org/entry/3808773 | https://logbooks.jlab.org/entry/3808773 ] 
        * Because it was clear a problem with the occupancy, I agreed to flush the target twice to discard it as issue. 
        * 
            * Restoring the data taking, there were not significantly improvement. 
    * ~22:00 Beam down for ~2h. 
    * Nikolay Markov called indicating that he was not allowed to enter into the accelerator area because he didn't fill the paperwork on time. 
    * 
        * Carlos Ayerbe is taking the Owl shift for him

Unless IT IS REQUESTED BEFORE 10AM, we WILL NOT have the RC Daily Meeting, especially when shutting down work will start around 10:30. 

Disclaimer: There could be a meeting to discuss future work and analysis, but I don't think that it has to be Hall related. It could be later.
