2. AD TE/EPC : removal old power supplies completed in the AD hall. TE/VSC : – UHM3107 and UVM3207 tanks : seals installation next week. – Ion pump change in still progress until early September. TE/MSC : BHN06: new CERN visit to manufacturer for first coil test this week. Waiting for feedback before final decision. An ultimate planning has been prepared, with delivery of the coils mid of October. In case of additional delay, the plan-B would consist in repairing BHN23 or 24. TE/ABT : – Provisional gasket installed for leak test in the workshop (TE/VSC). – Delay for the 2 KFI tanks reinstallation, fixed on 18/10 (compatible with the revised bake-out planning).
