Description
Summary of the meeting is available here
In Europe, the CERN Council has charged the Laboratory Directors Group (LDG) to develop the Accelerator R&D Roadmap for the next decade before the end of this year. This Roadmap will consider different funding scenarios and contain deliverables and demonstrators. Council is expected to decide on the Roadmap by the end of the year. As a consequence the Roadmap will define the R&D for the next decade. In this frame a Muon Beam Panel has been created by the LDG. In order to prepare the Roadmap we plan to hold three community meetings. This first community meeting will take place in May 20 and 21, the second at the end of June or beginning of July and the third at the end of August or beginning of September. These meetings will serve to provide the input to the Council meeting in June and September and to the main European Physics community event, the EPS-HEP Conference.
Deliverables for the Roadmap:
• Should focus on concrete programme that we want to propose.
• What is needed as input for next Strategy Update?
– What will be objections to the muon collider concept?
– What do we need to support to be scientifically sound?
– What do we need to have ready for the test facilities?
– And the other R&D programme?
• Probably should think in terms of scope from the beginning: for each R&D item, define required level => Initial proposal:
• What is needed as input for next Strategy Update?
– What will be objections to the muon collider concept?
– What do we need to support to be scientifically sound?
– What do we need to have ready for the test facilities?
– And the other R&D programme?
• Probably should think in terms of scope from the beginning: for each R&D item, define required level => Initial proposal:
- no work needed;
- concept, basic parameters;
- lattice, reasonable basic performance specifications;
- lattice with tolerances, advanced performance specifications;
- conceptual design;
- engineering design;
- model, test of specific parameters;
- prototype.
• In parallel, define risks.
Charge for this First Muon Community Meeting: The goal is to identify the R&D that has to be carried out before the next ESSU-PP to scientifically justify the investment into a full CDR for the muon collider and the corresponding demonstration programme. This includes R&D to develop a baseline collider concept, well-supported performance expectations and to assess the associated key risks, cost and power drivers. Further, the main components of the demonstration programme should be identified together with the corresponding preparatory work. The working groups should propose realistic but ambitious targets for the performance goals of the different collider systems. In particular they should consider what could be assumed for the demonstration programme, i.e. in one or more test facilities starting in 2026, as well what one can anticipate to be available in 2035-2040 for a first collider stage and in 2050 for an energy upgrade.
