Results of Annual Review Thanks to all who participated in the review, The presence of the IK partners in both the poster session and in giving talks played a major role in impressing the committee with the scope of work accomplished to date. Additionally, we received a number of compliments from the committee on the quality of the talks presented by both ESS staff and IK partners. Overall, the results of the review were very positive: “Impressive progress is being made towards delivering the world’s most capable neutron science facility, with the project now 52% complete.” “The overall scope of the in-kind contributions is unprecedented and the methods developed to manage them have been remarkably successful despite the anticipated difficulties.”

Results of Annual Review The single overriding recommendation of the committee for ESS as a whole was: “The Committee believes that resources laboratory-wide should now be focussed on achieving at least the minimum criteria for a “day 1 of science” milestone. This will necessitate postponing activities which are not needed for the new focus, and reallocating resources between the key project areas (CF, Accelerator, Target, NSS).” This is clearly a lesser goal than “Start of User Program” How ESS will interpret this recommendation and apply it is under discussion. Given the nature of the accelerator, this recommendation will likely have a minimum effect on ACCSYS. The committee does recognize the challenges that ESS is facing: “This narrowing of short-term focus is especially important given the observation by all subcommittees that schedule & cost contingency are very likely to be insufficient. “

Results of Annual Review Specific Recommendations for the Accelerator subproject were: Incorporate lessons from source/LEBT commissioning into the plan for future commissioning stages. Strengthen the operation group as early as possible, and involve system experts. Organize a mechanism for smooth transfer of knowledge between the IK partners and ESS staff.

W02-2019: Accelerator Week Progress: Preparations underway for upcoming “Work Camp” on operations and staffing Completion of TS2 bunker sufficient for installation of cryodistribution line. The installation work starts this week. The Vacuum team and Procurement finished the documents for the Turbomolecular pumps and Vacuum Catalog bid process. It is planned to the published end of second week of Jan. Issues: Delay in restart of Ion source to later in January due to need to procure a replacement power supply – This illustrates the spares issue In order to address CE Marking concerns, ACCSYS proposes that CE marking becomes the long term ambition for all ESS systems and that the Quality Division is charged with the task to assure that IK partners will do the minimum required for CE marking before the end of IK contracts. Discovered an interference issue between the DTL intertank apertures and the Faraday Cups - working with Legnaro to resolve it. Held a productive meeting with ICS to review and address issues with the IOxOS platform - a path forward to the BLM CDR is emerging. In-kind: CEA visiting ESS the 11 Jan to plan for RFQ installation. CDR for LLRF NC linac, from ESS Bilbao in Lund on January 15 ESS Bilbao experiences issues with the high power RF load for klystron reconditioning Upcoming Meetings: 28th Accelerator Technical Board Meeting January 17. Visit by J. Stovall to discuss warm linac installation and operation See also action list and weekly minutes at: https://confluence.esss.lu.se/display/ACCSYS and list of weekly slides at https://confluence.esss.lu.se/pages/viewpage.action?pageId=227680319

Primary Goal: Beam through at least the RFQ by the end of 2019 Major Goals for 2019 Installation of the RFQ, MEBT and first DTL tanks in tunnel Installation of infrastructure for tunnel and RF gallery Commissioning of cryoplants completed and installation of cryo-distribution system completed Test stand 2 in Lund in operation 2 medium beta cryomodules assembled and 8 spoke cryomodules assembled NC , spoke and Medium beta RF systems installation ongoing with system operational for NC linac commissioning HEBT installation completed with magnets and beam pipe Integration of P6 Installation Plan into the P6 Live plan and infrastructure project plan in P6. Primary Goal: Beam through at least the RFQ by the end of 2019
