4. Ten Triple-GEM Detectors Transfer of know-how from GDD Eight detectors built at CERN (30cm  30cm active area) Two detectors built at Florida Tech using innovativeconstruction method Both detectors working 8 keV X-rays mips M. Hohlmann - Florida Tech Statement on Participation in CMS High-eta Muon Upgrade Project

5. R&D - CMS High- upgrade New, cost-effective GEM foil thermal stretching technique via infrared heating under clean room conditions in our high- bay lab (RD51 Technical Note in prep.) CMS high- prototype drift foil Works well ! along long side of frame M. Hohlmann - Florida Tech Statement on Participation in CMS High-eta Muon Upgrade Project

6. Readout Electronics & DAQ RD51 is developing a commonScalable Readout System for MPGD’s : • from few 100 to ~105 channels • full hardware chain currently being tested Hans Müller Sorin Martoiu (CERN) VFAT here for CMS high- det. common DAQ part – could be used for CMS high- GEMs • Florida Tech’s current contributions to Scalable Readout System • Trying to get commercial production of ~200 hybrid front-end PCB’s going (for APV25 chip) • DAQ software development (DATE for SRS) together with ALICE DATE experts • Event monitoring (AMORE for SRS) with ALICE DATE experts • First demonstration of chain APV+SRS+DATE+AMORE achieved • First integration tests of SRS with our 30cm × 30cm GEM detectors • Largest projected user of SRS to-date (~15k ch.) APV25 test pulses with a 128 ch. readout M. Hohlmann - Florida Tech Statement on Participation in CMS High-eta Muon Upgrade Project

7. Proposed Fl. Tech Contributions to CMS High- Project • Long-term • Main interest: GE1/1 Detector Production & Testing Site • Expand current setup in clean room for parallel production • Adapt SRS DAQ for detector testing procedures • Set up cosmic ray stand and X-ray source for post-production testing • Secondary interest:DAQ & Event Monitoring • Adapt s/w for VFAT if CMS decides to go with an SRS-based system • Short-term & Medium-term • Set up GEM foil testing box (measure leakage currents under gas) • Construct and test a prototype detector (following current CERN design) at Florida Tech using our IR stretching technique • Contribute to beam tests of prototypes • Continue R&D on series production techniques M. Hohlmann - Florida Tech Statement on Participation in CMS High-eta Muon Upgrade Project

8. T3 Available Facilities • GE1/1 Production & Testing • Large clean room for production (~ cl. 1,000) • Small clean room for R&D (~ cl. 10,000) • Space in 350 m2 high-bay area for test stands • Gas detector lab (HV, gas supply & monitoring, 10 Gs LeCroy scope) • Construction materials (e.g. glues, coatings) • GE1/1 DAQ Development • Spare SRS r/o components expected • Dual SRS use for 30cm × 30cm GEMs and for CMS high- GEMs can be anticipated • DATE & AMORE software • CMS Tier-3 Grid Site • Offline data analysis • Can be made available to high- upgrade collaborators for extensive simulation work High-Bay experimental area M.

9. 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
