  1. TASK H/EMU CMS EMU CMS Cathode Strip Chambers Production Status at FNAL Yuriy Pischalnikov UCLA

  2. Panels Production Status (LAB8) CSC Assembly Status(MP9 facility) CSC Validation Status(CRTS at LAB7) Foreign Factory Setup Chamber Integration efforts Status of FNAL Activity

  3. FNAL Activity LAB7 Cosmic Ray Test Station Validation of first 20 CSCs PNPI Site parts and critical tooling (smaller chambers) smaller CSCs+Electronics, tested installation/commissioning UC Site large CSCs large CSCs+Electronics, tested installation/commissioning Fermilab Site: - panel production - large CSC assembly CERN large CSCs+Electronics, tested installation/commissioning large CSCs UF Site Procurement parts and critical tooling (smaller chambers) smaller CSCs+Electronics, tested installation/commissioning Wire Panels IHEP Site Guard strips Gap bars (UF) Wire fix bars Frames (FNAL) HV Connector (UF) Frames/HV Connector (UW) Etc.

  5. FNAL Factories - Lab 8CSC Panels production Facility

  6. LAB8Panels Production Rate 100% (148CSC) of ME23/2 at November 10 135 ME2324/2 Chamber(~91%) 19/950 Rejected Panels (2. 0%)

  7. LAB8 QC/QA of Gerber operation:CMM measurements of strips position

  8. LAB8 QC/QA of Gerber operation:CMM measurements of strips position • Accuracy and repeatability of Axxiom and Gerber • operation measured for ~20 different CSC panels withCMM • Gerber’s strips art-works operation • accuracy - 2,5mm/strip error = 200mm (8mills) for 80 strips • repeatability better than 1mills • Axxiom holes drilling operation • accuracy ~10mills • repeatability better than 2-3 mills

  9. Panels ProductionQC/QA Rotation X 1st groove 81st groove For ~50% of ME234/2 panels, alignment marks analysis shows good quality and a process under control Y Scale 81st groove 1st groove Off-set

  10. Y 1st groove 1.000 81st groove #3 #2 #1 #6 #5 #4 X Z X 6.000 -6.000 1st groove 81st groove 1.000 Panels ProductionPhotogrammetry Techniques to transfer Strips position outside of Chambers • Cross-check on strips position after chamber assembly (typically @ CERN) Excellent correlation between CMM and Photogrammetry Measurements
