15. GEM foil tests in CO2 have been done by applying HV to each GEM and measuring the current.Nothing suspicious has been found. The drift was also tested up to 3.5kV, measured current was constant 0.3nA.6/24/201115Rui De Oliveira
16. 16Next step for the small protoSmall prototype in the setup, connected to the gas.The next step is to make full set of tests (gain, uniformity)6/24/2011Rui De Oliveira

20. Goal: Set up a production line being able to face most of the future requests for large GEM productions (from 1 piece to few hundreds, size up to 2m x 0.6m) First step: Machine procurement and installation-The purchasing process is ended-We have bought 3 new machines-1 machine is in operation-2 are still at the installation process level planning : 3 machines running September 2011Second step: -redefine all the process parameter related to the new equipments-Build some prototypes of the # detectors We are in the process to hire a technical engineer for 2 years (AIDA Funds)Machine investment for GEM production6/24/201120Rui De Oliveira

26. The Consultant company designing the building have been selectedThe preliminary design is about to be completedThe market survey for construction should be launch soonThe final design will be done with the consultant and constructorThe construction should start beginning of 2012The construction should end Mid 201340 square meter room reserved for MPGD assemblyAll the machines for large size detectors production are in the layoutArea 900 m2 1400m2 with optimized layoutMost of the baths will be replaced by compact machinesRooms are reserved for new processes (laser and plasma)New building 1076/24/201126Rui De Oliveira
27. GEM single mask process is stable CMS project can be done at CERN if neededThanks to new equipment the prices will dropThe new stretching method can reduce a lot the assembly timeBuilding 107 will help again to reduce prices.Conclusion6/24/201127Rui De Oliveira
