Orsay, France
The second Collaboration Meeting of the Muon Collider Study will take place from June 19 to June 22, 2023. The meeting will be held in person at IJCLab in Orsay (France) and it is organized by CEA, CERN and IJCLab. We plan to cover at the meeting all areas of study and development, allowing ample time for both plenary and parallel sessions. The main goals of the meeting will be to report on the progress of the study, in accordance with the defined work programme, and consolidate the share of tasks among all Collaborators, including the activities within the scope of the EU-funded MuCol Design Study. We especially wish to use this opportunity to address interfaces and integration among the various activities. The meeting is an opportunity for the Collaboration to review activities, advances and plans. The final plenary and close-out session of the Collaboration Meeting will be followed by the first session of the Muon Collider Synergies Workshop. This meeting is also supported by MUST, the MUon collider STrategy network, a part of the I.FAST European project, whose specific objective is to support the effort to design a muon collider and to project and plan the required R&D, while consolidating the community devoted to develop an international future facility. | ![]() |
