Plans & Aims for April + May

• Commissioning of all beam line magnets.• Running MICE in parasitic mode.• Detectors and DAQ.• Miscellaneous

M.Ellis

Beam Line MagnetsM.Ellis

Beam Line Magnets

• Magnet power supplies locked off and correct procedures (Method Statement + Risk Assessment to get Authorisation To Work) need to be followed to work on or with the magnets

• Water supply has been reduced from 100 L/min to 60 L/min, magnets operated with an acceptable temperature rise.

M.Ellis

Spensley, Glover

Spensley, Govans,Long

Decay Solenoid• Achieved the major milestone of achieving liquid

Helium in the solenoid for the first time.• No major problems with the refrigeration plant or

the magnet.• LiHe filled to 5% of full

M.Ellis

Detectors and DAQ

• CKOV in place.• TOF due in mid May (?)• Tracker due in mid June.• Online monitoring software is ready.• First version of G4MICE unpacking code for

the DATE format has been written.• First version of online database design has

been produced. Work continues.

M.Ellis

Software

Gate Valve

• Gate valve has been opened.

• Target operation authorised by ISIS, who release key to MICE for data taking.

• First step towards parasitic operation...

M.Ellis

Miscellaneous• First web-cam installed.• Three more planned to be installed, hopefully

by CM21.• Shielding wall construction has begun.
