Time: 16:00 UK time
Attendance: Colin, Alan, Ken, Craig, Paul, Melissa, Ed

Aim: Provide a quick history so we may plan the next steps for the cryostat's.

Agenda and Minutes¶

Review of Cryostat 2 Status¶

• See slides Cryo2Service.pdf
• Discussion:
  • Disassembly is a big deal (AB):
    • To access cassette requires a complete cryostat tear down.
    • Thermal link fidelity not guaranteed (Cryostat 1 took 3 attempts)
    • Would require a FNAL team to perform tasks, maybe possible for September.
  • RTV seal used for wave guides is getting old (possibly more leaky).

Plans for Cryostat 1,3,4¶

• Require a sample analysed from the cassette space to determine water contamination.
• Need to be prepared to take data in 2nd week of next cycle.
  • Should plan cool down and potential waveguide move accordingly.

Plans for Cryostat 2

• None.
