GEM Track RecordGEM Track Record• Construction and Testing of Triple-GEM detectors

– Small prototypes (2cm 2cm, 10cm 10cm) since 2004– Small series production of ten 30cm 30cm detectors in 2009 & 2010

• RD51’s Common “Scalable Readout System” for MPGDs in 2010– Software development for SRS DAQ system (in ALICE DATE environment)– Frontend hybrid card: PCB with APV25 chip (used in CMS Si Tracker)

• Two recent publications on 30cm 30cm GEM detector design and performance (IEEE NSS ’09 proc., NIM article submitted for SORMA ‘10 proc.)

• Four publications on GEM application (muon tomography, DHS)

• RD51 charter member (2008)• Assoc. Partner in CMS CUPID proposal (MPGDs) - Marie Curie ITN fellowships (2009)

• Active participant in CMS high- upgrade group since early 2010: Investigating production techniques for GE1/1 detectors at Florida Tech

– Stretching of CMS GE1/1 GEM foils– Honeycomb spacers

• Team: MH, 1 post-doc (Kondo Gnanvo), 4 grad students (Mike Staib, Bryant Benson, Lenny Grasso, Amilkar Quintero (grad.)), several undergrads

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.)

Readout Electronics & DAQReadout Electronics & DAQRD51 is developing a common Scalable Readout System for MPGD’s :

Proposed Fl. Tech Contributions Proposed Fl. Tech Contributions to CMS High-to CMS High- Project 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

Available FacilitiesAvailable 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

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
