  2. CSC VALIDATION Tests • 1. HV scan of all 6 planes with/without Cs137 (dark&source currents) (checked at MP9) • 2. Gas gain non-uniformity with Cs137 source (HV=3700V) *************************************************** • 3. ZERO DEAD channels (checked at MP9) • 4. Anode wire groups (64group/plane) efficiency measurements • 5. Single wire (group) noise rate (TDC) • 6. Gas gain non-uniformity with Cosmic Rays measurements (CFEB)

  3. 2. Gas gain uniformity measurementswith Cs137 source (HV=3700V). Chamber Configuration to Measure Gas Gain Uniformity With Cs137 (ICs from cathodes) Strip’s#10 Strip’s#1 Wire’s#1 Wire’s#8

  4. Cs137 profile

  5. Cs137 measurements: correction according radiation profilefor one layer (layer#6,ME23/2-003)

  6. Cs137 .vs. Cosmic Rays(ME23/2-003,layer 1) Cosmic Rays Cs137

  7. Cs137 .vs. Cosmic Rays(ME23/2-003,layer 3) Cosmic Rays Cs137

  8. Correlation between Cs137 & Cosmic ray

  9. Gas Gain non-uniformity for ME23/2-003Cs137 & Cosmic Rays

  10. 4.Anode wire groups (64group/layer) efficiency measurements Nikolai Terentiev

  11. 4. Anode wire groups (64group/layer) efficiency measurements Nikolai Terentiev

  12. 4. Anode wire groups (64group/layer) efficiency measurements Nikolai Terentiev

  13. Single wire’s group Noise (TDC) Nikolai Terentiev

  14. Summary • We have facility (&team) at FNAL to proceed with 10 (20?) CSC Validation (in parallel with Integration Efforts) • We have proved reliability of CSC Gas Gain Non-uniformity (GGN) with radioactive source (Cs137) (correlation between Source & Cosmic Rays) • We converged into 5 points test program • GGN for ME23/2-001(&3) less than 2.5 (based on Cs137; Landau Cathodes distribution and Anode’s efficiency curves)
