Support Needs If CMS decides to move forward on MPGD high-  upgrade, we would need external support to ramp up our effort. Potential sources: –USCMS upgrade management for FY11 Manpower: 1 Post-doc (~6 months), technician Prototype Production: Materials & Infrastructure Travel to CERN for test beams –DOE FY11 base funding (starting June 2011) Manpower: Post-doc, graduate students Production infrastructure, Readout system Travel to CERN
