LAB256 - RPC

  • All the gas from China arrived
  • Humidifier is dismounted for the moment to be put in the new rack
  • Review of the status of the gaps
  • [ ] Start with 30% CO2 to check currents and efficiency for GIF detectors
    • [ ] Compare the efficiency with last test beam
    • [ ] Compare the currents with the last HV scan done at GIF++
  • [ ] Check for availability of Fabio for 256 installation to be continued before starting
  • [ ] HFC test: summary slides of R-32
  • [ ] Check empty bottles to send back
  • [ ] Gas bottles: check for Ar + ppm of O2 or H2O for uRWELL characterization. Not ordering now, just to check availability
  • [ ] Measure the length of the removed cable from GIF to understand how long we need the new cables

LAB 256 - uRWELL

  • [ ] Finish commissioning of mixer/gas system and monitoring
  • [ ] Perform initial HV scans with premixed bottle
  • [ ] Start using the available radioactive sources
  • [ ] Check with RP the implications of having an X ray gun

ISE

  • [ ] Take the material from 904
  • [ ] Follow up measurements of ATLAS RPC

uLOOP

  • [ ] Check with Pieter and Stef the code
  • [ ] Start drawing hte electrical schema for Jonathan
  • [ ] Ask Daniel which humidity sensor they have in DT
  • [ ] Order the cheap filter

GIF

  • [ ] Check humidifier rust in other humidifiers at GIF and in MID ⇒ ASAP
  • [ ] Restart at GIF changing the HV module and board
  • [ ] Change HV cables
  • [ ] Test again F- accumulation on the gas system

Other

  • [ ] Mixer from ETH ⇒ sending a volume filled instead
  • [ ] Review the status of the humidifiers (linked) with GIF task above)
  • Summer student:
    • One for RPC, strong computer skills
    • Analysis and recuperation
    • Possibly one for uloop and monitoring tools for gas systems
