SY-FCC workshop

Description
Aims of the Workshop
In view of the forthcoming delivery of the FCC feasibility study (FS) report in March 2025 and the pre-TDR for a Project decision in 2027, the SY-FCC workshop in October aims at evaluating the SY deliverables to allow the FCC project to:
- prepare the pre-TDR work, and refine the common understanding of technical objectives and organisation
- complete the FCC-ee infrastructure definition (underground & surface, including pre-injector)
- to assess its compatibility with a future FCC-hh machine (tunnel cross-section & space reservation at surface)
- identify together any important remaining open points for the FS
The FCC project will present the overall timeline, expectations and work organisation.
The SY technical groups will present the WP scope, organisation (including reporting and interfaces), and technical status of their FCC works to be able to deliver the FS and pre-TDR.
Importantly, each team will identify what is missing in terms of resources or input, in particular from other WPs/Groups.
Since the FCC week in mid-2024 provided a comprehensive overview of the technical status of most of the SY activities, it is not foreseen to repeat the detailed technical presentations. Instead, the idea is to focus on how to deliver the FS and pre-TDR information needed on time, and to make sure that the SY Groups and the FCC project have a common and shared understanding of the objectives, priorities, work organisation and challenges to solve together.

FCC project status 30m
- FCC timeline and progress with mid-term review recommendations
- Present baseline, machine parameters and optics; is a major evolution needed/expected in the pre-TDR phase?
- Timeline, status and assumptions for cost exercise: what is included and what is not included (workforce, R&D, spares, …)? which time period is covered by the cost exercise?
- Expectations and priorities for the pre-TDR phase in terms of machine design, equipment design, and R&D for SY systems; in particular, which level of detail is expected for system/equipment design?
- Strategy for the project work organisation, interfaces, processes and WBS for the pre-TDR phase (2025-2027) and afterwards (from 2028), in particular: how are equipment groups/specific study groups present/represented in the overall structure? formalization of work packages? is a second-layer management below the pillar management needed/foreseen?
- Technical baseline and change management process: how is all the information collected across equipment groups/study groups? which bodies take decisions? how are decisions documented and communicated to equipment/study groups? interplay between accelerator design and technical design?
