Presentation transcript:

Action Who Progress made status Implement central repository for drawings -- need detector information to add to official drawing WL Progress on-going. Liasing with Ghislain on CKOV2 drawings; Maurizio on the TOFs and Tortora on Calorimeter etc Also with Geoff Barber on Tracker mechanicals. On- going Instrumentation for absorbers must be specified and incorporated into design (temperature sensors, liquid level sensors, …) SI Check minimum gap between AFC & Tracker solenoid Module -- Also check for floor bolting at various stages WL / UB FEA done. Floor loading seems reasonable for the AFC module. A meeting is being held on the 14 th Jan at RAL to discuss implication. Will check with Ulissee on how he get on with his calc on gap distance On going Continue working to define worst-case magnet forces and collect magnet design notes into design report MG Define absorber heater implementation YI / SI Revise absorber vent pipe size to make it adequate for He case WL Agreed to increase this to 15mm diameter. Drawing being updated done Get RAL seismic design criteria and verify that designs meet them WL/ PD On- going Status of Progress

Action Who Progress made status Evaluate stresses at module interconnect flanges and bolts SV Define RFCC module tie-in to rail system SV Work out gusset arrangement to transfer CC forces to RFCC module vacuum shell. SV Evaluate the need for redundant LH2 relief paths EB / TB Evaluate merits of cryocooler heater vs. 3-stage cooler w/o heater MG Evaluate absorber heat load with more realistic assessment of surrounding temperatures (is proposed MLI adequate?) EB/ MG/ SY Raised in the meeting between RAL & Oxford on 4 Nov. Action plan was outlined. Little progress made so far. Could Elwyn please follow up progress Finalize interface between radiation shield and detector module - must forces be transmitted WL Stephanie has done the calc. Will discuss this at the RAL meeting on the 14 th Jan. On- going Consider participation in KEK and/or Fermilab absorber tests (some coordination maybe called for) YI / SI Evaluate magnet interaction during quench -- does one quench induce others EB / MG Raised in the meeting between RAL & Oxford on 4 Nov. MG agreed to work with Holger on this. Some progress made. Mike Green needs to monitor progress Raise Change note on the radiation shield design SY / WL Done

Action Who Progress made status Window QC – round robin exercise WL Still awaiting for the window to be released from Fermilab. This is ridiculous and we need to do something soon to get this going stalled Understand QC requirements for absorber windows and assign oversight responsibility WL Need to discuss with the group on who is the best person to do this On going Hydrogen system R&D TB / EB
