Other activities LINAC 2: Remove 5 BCTs in LBE, LBS and LTB lines, endoscopy of RFQ and maintenance of pumping groups • LINAC 3: Replacement of ITH. BCT 41 and some LIU-IONs activities • 9/9/2020 Document reference 6

Resources • • • 2 teams of 2 technicians for PS complex (includes LINAC 2, LINAC 3, LINAC 4, AD and ISOLDE) In case of over-allocation TE-VSC will request prioritisation. We can only work on parallel activities if feasible. PSR – PSB. TE-VSC does not establish priorities or planning. We only give advice about the technical feasibility. All new or modified components must be vacuum acceptance tested before installation. Please send them ASAP. If one component has to be submitted during the YETS it must be included in the planning, as the same teams working in the machines carry out the vacuum acceptance testing. If components arrive late or are not accepted it will delay the installation. 9/9/2020 Document reference 7

Follow-Up • Share. Point site accessible to machine coordinators, to collect all requests, follow up ECRs and IMPACTs and check resources. 9/9/2020 Document reference 8
