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 have held one community meeting and plan to hold two more. The first community meeting took place in May 20 and 21 (https://indico.cern.ch/event/1030726/). The second meeting will take place from July 12 to 14 (https://indico.cern.ch/event/1043242/) and the third one will take place 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:
  1. no work needed;
  2. concept, basic parameters;
  3. lattice, reasonable basic performance specifications;
  4. lattice with tolerances, advanced performance specifications;
  5. conceptual design;
  6. engineering design;
  7. model, test of specific parameters;
  8. prototype.
• In parallel, define risks.
 

Charge for this Second Muon Community Meeting:
During the first community meeting we identified a set of challenges in the delivery of the muon collider. The goal now is to confirm those challenges and develop them into a prioritised and resource loaded R&D list.

In particular:
  • 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.
  • Identify the main components of the demonstration programme together with the corresponding preparatory work.
  • Realistic but ambitious targets for the performance goals of the different collider systems.
This includes R&D to develop a baseline collider concept, well-supported performance expectations and an assessment of the associated key risks, cost and power drivers. Also the working groups 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.
 
In order to support this activity, 11 working groups have been formed to discuss priorities in a number of areas, led by a selection of conveners. The conveners are tasked with leading and summarising the discussion in support of the Muon Beam Panel. As part of this work, the conveners should break down the work into packages and estimate, as far as possible, the resources required to complete the work.
 

Conveners of the 11 working groups (note that we are in the process of enhancing the working group conveners, so the following is subject to change: as of 15/06/21):

=> Working    groups    should    prepare    beforehand    and    only    finalise    at    workshop (R&D lists should be available before the meeting for discussion and finalisation during the meeting)!

=> Structure of the 3-day meeting:

  • July 12: plenary introduction, parallel working groups finalise list of required R&D
  • July 13: plenary: working groups present lists of required R&D and resource estimates
  • July 14: plenary: first prioritised list of R&D items, opportunity to express interest
=> The zoom info for the Working groups can be found (it is the same as for the first community meeting except that this time we will have 11 working groups instead of 9): HERE.
