8. Manpower Issues Even though the collaboration comprises ~80 people, much of the work is currently shouldered by a relatively small group of people. They are the ones that also participate regularly in the weekly technical working meetings. We need to engage all collaborators actively: –Task coordinators to identify specific tasks and manpower needs –Team leaders to identify expertise and interest of their team members (ongoing) –Match needs with human resources (CB with task coordinators and team leaders) and assign people to working groups 6/24/2011 M. Hohlmann, 2 nd CMS Workshop on High-eta Muon Upgrade with GEM Detectors, CERN 8

9. Meetings Weekly technical working meetings (ongoing): –Detector R&D meeting, Tuesdays, 14:00 CET –Electronics R&D meeting, Thursdays, 14:00 CET –Trigger issues covered in CMS trigger upgrade meetings CMS weeks –Plan on having regular technical meetings of the GEM collaboration at all future CMS weeks –Also have a CB/IB meeting at every CMS week, e.g. at the end of the technical meeting 6/24/2011 M. Hohlmann, 2 nd CMS Workshop on High-eta Muon Upgrade with GEM Detectors, CERN 9

10. Funding In 2011, collaboration is “self-funding” with 3,000 SFr contributions to a common fund from each institution (cash or in-kind). This covers cost for prototype development and summer test beam effort The next steps towards more solid funding are –Produce Technical Proposal –Get approval by CMS as official upgrade project –Approach various national funding agencies for project funding For details, see Michael Tytgat’s talk (next) 6/24/2011 M.
