The ESS is an In-Kind Collaboration ICS Partners The ESS is an In-Kind Collaboration Requires a lot of Coordination! For smooth efficient installation and good operation we need: Standardization (Installation, Maintenance), Documentation (for Operation, Maintenance), Test procedures (Commissioning), Partner Involvement.

WoW for Operate Facility Assure that a consistent and cohesive organisation is in place to operate the Neutron Source and Technical Infrastructure.  Assure that operation of systems will be done in a safe manner with clear responsibilities and procedures.  Assure that operation of systems will be done inline with the ESS "Master Plan" and work in close collaboration with Installation activities and NSS goals. Operate the Neutron Facility systems and Technical Infrastructure by: Managing the operations programme for the Neutron Source Managing the maintenance programme and its schedule for the Neutron Source Interfacing to the Installations organisation and planning Interfacing to the NSS organisation and User programme Developing with NSS the operations schedule Providing support to all Technical divisions in their work for facility development

Transition to Operations We have an updated description of “Early Operations of the ESS Neutron Instruments and first scientific results” (ESS-0420218) that has distinguishing successive stages: Up to Beam on Target (-July 2022) ESS initial stages (July 2022-December 2023) Early Days: BOT to (BOT + 3 months) (July – September 2022) Consolidation Days: The next 3 months: (BOT + 3 months) to (BOT + 6 months) (October – December 2022) Performance Assessment days: (BOT + 6 months) to (BOT + 9 months) (January – March 2023). First Performance Demonstration Days: (BOT + 9 months) to (BOT + 12 months) (April – June 2023) Ramp up and Early Science: (BOT + 12 months) to (BOT + 18 months) (July – December 2023) Start of the ESS User programme SOUP (2024-2027)

ESS high level structure during Initial Operations Items successively covered during the initial stages Principal activities: Satisfy SSM requirements, Target Studies, Test Beamline activities, Instruments & hot commissioning, improve staged availability & reliability, benchmarking, choose 1st 3 Instruments for SOUP, 1st scientific results, maintenance. Proton Beam Parameters for Users: steady power increase from 100 kW (Jul 2022) to >570kW (Jan 2024) to ~2 MW (12/2025 End of Construction).
