  2. Introduction: the CMS GEM Endcap system GEM Detectors Superchambers GE1/1 GE2/1

  3. GE1/1 Detector Layout

  4. MASS : 9,2 Kg Recent 20mm elongation In this direction (HV Div.) III GEM WORKSHOP

  5. III GEM WORKSHOP

  6. GE1/1 Prototypes – Proto1Readout PCB with strips 0.8mm pitch 128 channels per VFAT connector 1.6mm pitch 256 strips for each eta partition PCB thickness = 3mm 1024 channels

  7. Figure1 The HV divider

  14. 4 detectors completed NS2 Technique • No spacers in active area • Assembly time : 2 hours • No gluing, no soldering • Re-opening possible • GEM exchange possible • No stretch degradation with time • Stretching more intense

  15. Power supply Ceramic divider distributing the High Voltage among the 3 GEMs

  16. Gain calibration CMS – GE1/1 – NS2 prototype

  17. Gain calibration • For each sector (24 readout sectors) : • Counts VS chamber HV supply • Output current • Position of the X-ray peak • We want to see if : • The gain is uniform for all the readout sectors • All the sectors are working • The GEM stretching system is suitable • Gain VS chamber HV supply

  18. Gain calibration Experimental Setup Prototype 1 Copper X – ray (8KeV) Holes Electronic modules • Gas mixture Ar - CO2 (70%/30%) • Gas flow : 5L/hour

  19. Gain calibration Chamber 1
