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
