Status of MICE Muon Beamline {{>toc}}

This list is for tracking the state between BLOCs, and should be viewed before an expert is called. This is complementary to the whiteboard in the control room.

Access / Construction Work¶

• Hall is open.
• PRY construction continues - hence crane activity

Interlocks and Controls¶

• Target gate valve is open
• Beamstop is closed

Services (electricity / water / air / air-conditioning / network)¶

• No service interuptions scheduled.
• Airconditioning unit 1 is isolated, the others are operational.

Systems¶

• Beamline:
  • The beamline polarity is set to mixed polarity
  • Control boards have been swapped between Q4 and Q5 MPS to look into ramping issue.
• DS:
  • The Linde Fridge is running
  • The PSU is isolated from the DS, and undergoing testing to look for overtemperature trips.
    • If it trips, leave as-is (do NOT reset interlocks) so that the specific channel can be identified
• Proton Absorber:
  • need to further close damping valves
• Beamstop:
  • Powerpack 2 has a cracked hose fitting awaiting replacement and is out of use
• MLCR:
  • No issues
