      Mechanical structure:

      • installed 8 20x20cm2, with the same configuration of last 2 years TB, and 2 µRWELL 50x50cm2 
      • all the supports for fans have been installed
      • all the supports for the VMM3a hybrids are now in place

      • handling request foreseen for Monday at 9:30 am, https://edh.cern.ch/Document/SupplyChain/SIT/11917487
      • internal transport on Tuesday at 10am, https://edh.cern.ch/Document/SupplyChain/SIT/11917503
      • TO BE REMINDED:
        • the centre of the structure is at 124cm, while the beam height is at 138cm
        • asked for some bricks and shims to reach the needed quota

       

      Gas:

      • request at the following link ; just a reminder to check on wednesday that they will not put the ArCO2Iso in the flammable gas area
      • ArCO2, ArCO2Iso will be provided by gas team
      • ArCO2CF4 are stored at GDD gas area (154/G0-922F); the following bottles can be used (in red the code written on the bottles)
        • Gas rent./CRFDGCY001-0BA168NEA        
        • Gas rent./CRFDGCY001-0BA1GP12N        
        • Gas rent./CRFDGCY001-0BA12AKY6        
        • Gas rent./CRFDGCY001-0BA1GP0AK      

       

      Pool:

      • HV board
      • 2 crate nim (one for CR, one for experimental area)
      • discriminator, fanout, dual timer, scaler
      • delta power supply for fans
      • 5 attenuators (trigger, scintillator with hole, 2 cherenkov, 1 spare)

       

      Micromegas chambers

      • understood the issue: drift vias was not so deep enough to put in communication HV pin and pad on the RO PCBs

       

      Electronics

      • VMM3a PC (from RM3/Na)
      • 1 SRS crate (from Bari)
      • 3 FECs (2 from bari, 1 from RM3/Na) -> look for one more FEC
      • 3 DVMMs (2 from bari, 1 from RM3/Na) -> look for one more DVMM
      • 1 CTF (from Bari)
      • 32 VMM3a hybrids (16 from bari, 8 from RM3/Na, 8 from CERN)
      • 32 LV cables (from CERN)
      • 4 PBXs (2 from Bari, 2 from CERN)
      • most probably we need to change the firmware on all the FECs

       

      HV:

      • mainframe hostname:  mpgdbari-sy
      • HV board:
        • A1833N set at VMax:4kV, IMax:2mA, IRes: 200nA for Scintillators and GEMs; manual: https://wiki.infn.it/_media/strutture/lnf/da/btf/dispositivi/a1733b-a1833b_rev10.pdf 
        • A1821N set at VMax: 3kV, IMax: 20µA, IRes:2nA for MM/µRWELL drift
        • A1821HN set at VMax: 3kV, IMax: 20µA, IRes:1nA for MM/µRWELL readout
