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 M. Hohlmann, 2nd CMS Workshop on High-eta Muon Upgrade with GEM Detectors, CERN

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 M. Hohlmann, 2nd CMS Workshop on High-eta Muon Upgrade with GEM Detectors, CERN

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) M.
