Tasks for Roger starting at CERN

• Systematically collect of all information– on the Central Solenoid System and put into the ATLAS databas;

CDD/EDMS/…

• Co-work with ECR for proximity cryogenics test in June2002,– Physical layout,– Control and monitoring,

• Interface with LAr calorimeter– SC bus-line design to be frozen,– Installation work plan,

• Confirm/re-evaluate magnetic force– Magnetic force with LAr support frame in B180, and with hadron

calorimeter in Ponit-1.

A suggestion given byHerman ten Kate

• It may be wise/valuable to consider thatCERN/ATLAS will manage to include furtherman-power works at CERN;– Such specific works of Superconducting joints, pipe

joints, and monitoring signal wiring,

• It may be realized;– if Japanese F.T. budget could be allocated to this

further works at CERN.

• It will be further studied and– discussed between CERN ATLAS and KEK.
