        IMPACT Declarations 2021 : 

        During the Christmas Closure, all active IMPACTs will be closed.
        For 2021, please prepare a new request, with "GIF - Irradiaton 2021" as intervention period.
        If you clone the one from 2020, please review the description and the participant list !


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

        User Meeting 2020 : 

        We expect a report of your ongoing measurements, and outlook on what is needed during the rest or LS2 and - most importantly - an outlook for your 2021 beam requirements.
        Currently proposed date : TUESDAY 26.01.2021

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

        Annual Irradiator Maintenance :

        Default date is first week after Christmas break.
        Not able to confirm this yet due to unclear CoVid-19 situation and travel restrictions. 

        Annual access system Maintenance:

        Scheduled for next week on Wednesday 09th morning. It will take half a day. During the maintenance the GIF++ will be operational (weekly access). Once the maintenance is over, there will be only a patrol to do in order to test that everything is working fine (it will last for few minutes). 

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

        Preparing Christmas shutdown  : Gas requirements for the closure !

        Please provide us with your plans for the Christmas closure, and in case you need to flush your detectors, with the gas requirements for the 2 weeks.

        ATL-MM -> premixed bottles 10 l/h Ar-CO2 - 10l/h Ar-CO2-iC4H10

        ATL-sMDT ->   no flushing during Christmas holidays

        ATL-sTGC ->  not yet sure but in case the chambers will be flushed with only CO2 ~ 6l/h

        ATL-RPC  ->   no flushing during Christmas holidays

        CMS-DT ->    Ar-CO2 20l/h

        CMS-CSC ->  Ar-CO2 20l/h 

        CMS-RPC ->  no flushing during Christmas holidays

        EP-DT1 ->  1/2 l/h of Argon 

        EP-DT2 ->  1/2 l/h of Argon 

        ecogas ->  no flushing during Christmas holidays

        WILL BE UPDATED DURING THE MEETING !!!

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

        Weekly Planning :   https://teamup.com/ksvh7dak8mub8k7xpe 
        UPSTREAM :          Default filter settings :  2.2  (10 from 3. Dec until end of year)
        DOWNSTREAM :   Default filter settings :  1

        T.B.C. next week if we can move the weekly access to Thursday 17th (day of the GIF++ shutdown) instead  of Wednesday 16th

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

        ATLAS-MM :
        SM1 long term chamber inside bunker (2-3 months). IC4H10 test ongoing.
        3 long term chamber placed (on the ceiling) + 1 quad installed yesterday WED 02nd. It will be swapped next week with another quad.

        ATLAS - sTGC :  New chambers arrived, under test. Problem with the gas system has been solved. Multiple test campaign will follow in order to catch-up with the time lost during last week. More chambers arriving from Chile, that needed to be tested urgently. In case, there will be no time to do this tests, the chambers will stay in the prep.area and will be flushed with CO2 over Christmas        

        ATLAS-sMDT   :  Some noise problem currently under investigation (getting better). From today till end of the year will take data with attenuation 10. Gas quality will be changed from class II to class III. 

        CMS-CSC:  Issue with cooling - solved.  Still some issue with the gas system (O2 / H2O sensor).
        Setup in the original position connected to the gas supply.

        EP-DT1:   Mara back to GIF. The setup has been removed from the irradiation area and put it aside in the bunker.             

        EP-DT2 :  One chamber installed in the EP-DT2 trolley. The aging test with eco-friendly gas mixture are going well. Most probably one more chamber will be installed next week.

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

        EcoGas:  New detector installed. Test campaign resumed using standard mixture (R134a, iso-butane, and SF6) 

        CMS-RPC:  Small trolley installed and operational since last week. Radiation program resumed on trolley 1.

        ATLAS-RPC: Coming back mid December.

        introduction, goal of the test, plan, needs

        BLM measuring campaign announced / ≈ 100 BLM, 6h approx. Week 45 (November 2nd till Friday 6th ). We will arrange everything in a way that the setup could be installed inside the bunker in the upstream area near ATL-sTGC setup    -> postponed until next year

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

         
        Bulgaria academy of science -> testing of new type of radiation monitor system

        A new setup of ALICE-RPC will come. More news in coming weeks.

        Gas recuperation system to be installed - Responsible : Roberto
        4 additional racks in Gas Service area. One containing flammable gas.
        FG detection system to be installed, power needs to be provided.
        (DELAYED by a few months. Will be first installed in CMS, and only later come to GIF)

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

        Gas usage at GIF :  we need to compile a table of gas mixture / consumption

        - 2 chillers unit installed and in operation from yesterday 28/10. They have been installed in order to face the shutdown of the general cooling system of the entire EHN1 - general cooling system expected to be back end of January 2021

        - R134a supply went off yesterday Wednesday DEC 02nd around midday. It seems that the issue is the main pressure regulator form the building 909 (picture attached). The same problem happened again this morning Thursday DEC 03rd. EN responsible are aware and an action will be taken by the end of the day.

        - ATL-sTGC gas system went OFF multiples times last weeks. After investigation and different tests, it seems that the problem was due to a faulty flow cell. It has been replaced and since yesterday morning the system is running.  

        - yesterday WED 02nd during the weekly access, the PPE and PPX of the GIF++ bunker were forced. Even thought it was really strange, after investigation with BE-ICS colleagues, the problem has been solved re-arming both doors. A maintenance has been scheduled for next week on Wednesday in order to check possible communication and mechanical faults.

          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.
