- DC Update:
Activities mainly LH2 work and Tracker cryo saga: seems to be a lot of air getting in. Lots of RGA scans- Tracker Issue
Cryostat 2: followed the official procedure for warm-up and cool-down. Have lost 12% of channels on one cassette and 27% on the other. Thought to be due to aging seals.
Pump/purged Cryo 3 yesterday, today see 13% N2. Think there's an air leak in. Try a pump/purge excluding the cassette space to see if the leak is at the cassette or the plumbing.
Also had a "Low Lid Temperature" alarm and a backing pump fail on Cryo 2 today. - LH2 Update
The LH2 Quench test with Neon will be in June (no CC magnets this cycle).
Hope to be ready to start cooling today - final vacuum and leak-checking - and start cool-down tomorrow. Still need to fix the quench line before the real LH2. FC will stay in position this cycle.
- Tracker Issue
- MOM Update
Expert start-up yesterday: The wrong absorber got written into the CDB, else OK (note have no Trackers).
AKurup wants to try new ALH tonight.
Beambump tune today: search Hall at 4 - with LH2 and Tracker work, better to postpone till tomorrow. We need ISIS BLM info to be getting into EPICS.
Daily Run Meetings will be (in ISIS coffee lounge) at 2 p.m. so that we know how the Hall work is going that day.
Next tranche of Shifter training will be on Monday.
- AOB
TOF1 has been replaced in position and the plastic sheet removed: it will need a survey.
