        IMPACT Declarations 2021 : 
        Please update the label on your setup. (Needs to start with 16xx or 17xx)

        ----------------------------------

        Various System Maintenance  next week - DONE
        Two days of Access System unavailable.
        March (2nd-3rd)  - During these 2 days the source will be OFF.
        + Ramses modification
        + gas detection system

        -----------------------------------

         Gas detection annual maintenance - DONE

        One day of maintenance. It will happen on March 3rd. Access to the bunker possible.

        - Testing  flammable gas supply valve power off -> iC4H10 will go off for some minutes
        - Testing the flashing lights and local sirens

        Please be aware that on Thursday March 4th, the EHN1 evacuation alarm will be triggered, for some gas detection test in the neutrino platform. In any case it will happen before 8.30am

        ----------------------------------

        RP modification of the read-out electronic of the radiation monitoring - DONE

        One day of maintenance. It will happen on TUE March 2nd. Access to the bunker possible but source OFF.

        ----------------------------------

        New gas installation request for NA61 & NA64: 

        Proposed date: together with the annual maintenance in the week 18 (03-07.05)

        Installation of a new gas patch panel for the NA64 (upstream GIF++). In principle we will need to stop the neutral gas supply for 1h in order to connect a two ways valve starting from our patch panel in the preparation area. In the meantime, also the iC4H10 line will be stopped at least for half a day. It will be needed in order to connect on the same line (bldg. 909), a new one for the NA61 experiment.   

        ----------------------------------

        Irradiator Maintenance  :   NO OPERATION  !  LIMITED ACCESS !

        Scheduled  : Week 9  (01-05.03)  Cancelled because of COVID-19 restriction
        Fall back    : Week 18  (03-07.05)

        ----------------------------------

        GIF pyTIMBER  :   Not opertional

        Changes to access TIMBER (authentication required)
        Retiring of access tools used. We will have to re-write the whole tool.

        Solution has been proposed.
        We need to see if this solves the issue.

        ----------------------------------

        GIF Logbook  :   

        Discussion started if we can move to accelerator logbook.

        Muon Beam Scheduling 2021 10m

        Preparation and Scheduling of Muon Beam Time 2021.
        Will be reviewed when we get the beam plan end of April

        Deadline passed. Beam request submitted to SPS Physics Coordinator last Saturday.

        North Area Physics : 12.July to 14.November 2021
        We expect to receive the first version of the NA schedule (including GIF) in end of April.

        We now need to start the space planning for the beam weeks.
        Please provide either a CAD drawing (preferred) or food-print (frowned upon) of your setup so we can see how / if they can be aligned along the beam line.

        ----------------------------------

        ATLAS - MM :
        3 long term chambers placed (on the ceiling), operational.
        New detector installed last week on the back of CMS-CSC.
        Another chamber (setup containing the iC4H10 mixture) in front of CMS-CSC in order to have a higher rate.
        Proposal to stay until summer. Discussion about position on site next Wednesday.

        ATLAS - sTGC :  Two new shipments this week. Starting testing.

        ATLAS - sMDT : 
        REQUEST : Running at Upstream 1 starting  today until next Wednesday. Fine with EP-DT if for one week only, waiting for CMS-RPC to comment.

        CMS - CSC:  Restarted irradiation. Gas purifier to be changed. Next week GC measurement.
        Upstream chamber preparations. Next Wed. upstream area - pulling cables.
        One rack in prep. area will be added as standard LHC blue racks.

        EP-DT2 :  System restarted. The aging test with eco-friendly gas mixture are going well. 
        Request : Once per month test with Ar, operated from a local bottle.

        CMS-DT:  Expected to return to bunker later this year. INFN still blocking activity outside Italy. 

        EcoGas:  New detector installed. Restarted. Test campaign resumed using eco-friendly mixture (HFO).

        CMS-RPC: Radiation program resumed on trolley 1. Some impedance problem to solve on the new chambers. Gas kill signal that didn't work when the R134a- FIXED. From now on, whenever a source OFF scan is needed, they are going to try to use the upstream abs set to 333 for most of the time. Indeed, there will be the need to switch OFF completely the source for few final step during the scan.  

        ATLAS-RPC: Coming back for the moment, not before March 2021.

        Monitoring of primary lines to be done. This year we will have the monitoring of the neutral gas (Ar/CO2/Helium/N2), instead next year it will be done also for the other (iC4H10, R134a, SF6, CF4 etc.). This signals will be then available in PVSS.

        On going discussion for main HFO gas supply line

          Guidelines for filling in IMPACT requests

          List of active IMPACT declarations : https://impact.cern.ch/impact/secure/activities/accessPoint/YDALC02-PPE154

          General Guideline : One IMPACT per setup.

          • two chambers on individual supports -> 2 IMPACT declarations
          • multiple chambers swapped on same or similar support -> one IMPACT declaration
          • basically, if you need two locations, please make two IMPACT declaration (clone)

          Each Setup should have IMPACT label attached with number.
          Attached documents : CAD file  or  picture.
          Review working hours : if your declaration includes the bunker area, please state the number of hours you want to stay INSIDE the bunker only (for RP purposes).

        • CoVid-19 5m

          CoVid-19 Risk Assessment for the Facility :  https://edms.cern.ch/document/2376286/1

          General guideline :

          • ONE setup to enter the bunker at any given time.
          • All presence at the GIF and access to the bunker needs to be announced via Teamup beforehand (!)
          • Traceability of people on site :  Logbook ! - List all the people you encountered.
