LN consumption as expected – no obvious leaks [~20% used per 24hrs]
35 slm recirculation could be reduced if we want to use less LN.
➔ Check if consistent with Anna’s calculations.
We used 6.0 Ar, 1x10-4 vacuum, didn’t use getter in inlet – look at decay constant (purity?) – Zoe
LN truck: we need ~ 2 fills per week?
TO DO: Evaluate LN need during filling/running then coordinate trucks.
TPC – Clevios chips not big problem
Solved problem of hanging plate holes, so need to mount MB on top.
Will install flanges/cables tomorrow
➔ List of actions needed to install everything
TPC and cryostat: 1.5 cm closest approach, 10 cm max distance
Need to clean cryostat etc. – ultra pure water?
Tagged source – FDC to investigate which sources are available
Cobalt-60? Sodium-22? Na22 best according to PS
YS/FDC check scintillators in lab
Also need cryopump – YS to discuss with Nicola
Report back on source/pump etc. next Monday
Internal note – Ashlea implemented GF comments
- ZB/GF to discuss tomorrow and upload to doc db
