28 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 June 2002, 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. 28

29 Works at CERN/ATLAS listed by Herman ten Kate (informed through T. Kondo, as of Sept., 2001?) 1 Work in B Cryogenics [Metselaar/Foussat] - Cryogenic HP+LP piping - Railing, work on platform - Transfer-line to BOC - Transfer-line installation - Transfer-line supports - Connections between CD and Valve box - Scaffolding - Installation (CD+VB+Chimney) - Installation Chimney 1.2 MSS in B180 [Sbrissa] - cables & connectors - modifications exsisting - quench heater supplies 1.3 MCS in B180 [Tyrvanien] - external cables (10m) - work for patch panel + miscellaneous - racks and racks installation - CPU+network cards - analog channel - digital channels - miscellaneous - software 1.4 Busbars/cables (second hand) modifications [Cataneo] 2 Work in Cavern 2.1 Final MSS [Sbrissa] 2.2 Final MCS [Tyvainen] - external cables (50m) - racks installation - racks - CPU+network cards - analog channels - digital channels - miscellaneous - software including SCADA bus 2.3 Power circuit [Cataneo] - mains etc - UPS - bus bars (CS part) - switch - ramp down unit - power supply 2.4 Cryogenics [Metselaar] - re-installation CD+VB+Chimney - piping between CD and VB (92m) - cables between CD and VB (92m) - transferline between CD and VB (92m) - modificationvalve unit (vac pumps, instrumentation) - connections to water, air, etc (not cryo) 3. Manpower - Roger Ruber and his exploitation expence 29

30 A suggestion given by Herman ten Kate It may be wise/valuable to consider that CERN/ATLAS will manage to include further man-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. 30
