  1. CMS RPC Endcap RE1 Status Report Schedule V34.1 April 05 Sep 05 • 2004 Milestones • 3 RE1/2 & 1 RE1/3 pre production chambers tested • Korean gaps deliveries • ISR Assembly Lab on schedule • CSC+RPC+LB Beam Tests • Cosmic QC 20 RE1/2+10 RE1/3 • 2005 Milestones • Production • 18 RE1/2 and 18 RE1/3 Installation April end • 60 RE1/2 & 60 RE1/3 • Installation October-November • Cosmic Tests / Magnet Test Preparation On behalf of Peking University Colleagues And all at ISR

  2. Dec. 2004 HV connector Last step Cosmic stand and DAQ RE1/2 Completed chambers ready for quality control tests in the cosmic stand

  3. Production Status: 20 RE1/2 + 30 RE1/3 Assembled Preparation gas pipes – 120 chambers Cables – 60 chambers Mechanics .. Cover closing Alu plates Chamber production rate Expected 5 per week March 20 RE1/2 mass production re-launch GOAL: June RE1/2 complete April end RE1/3 Gaps expected mass production re-launch GOAL: Sept 30 RE1/2 complete 36 needed @ X5 April 2005 Chambers Planned Constructed GOAL: Dec 05 All certified!

  4. Database developed to store RPC production information http://forwardrpc/cms_forward_rpc/production_db/Main_db.htm

  5. Create plots from cosmic test data Strip response profile

  6. Cosmic QCSee Andrey’s talk % HV 9.2kV mA Noise < 10Hz/cm2

  7. Chamber QC 4 Checklists At different stages of production Cosmic Tests : Andrey Waiting for Final Destination: Point 5

  8. Barrel and Forward (Endcap) RPC’s Configuration and Condition database requirements for CMS Core DB Team Document history - Following DB Workshop Jan 24-28

  9. Schema for RPC Barrel and Endcap See Marcello’s talk – DB meeting Wednesday 16 at 8.30

  10. Magnet Tests SX5 Cables & Services horizontal distances inside SX5 18m Counting House (see next page) HB HB 10m 10m 15m 49m YE+2 YE+2 YE+2 YE+1 20m magnet test position YE1 6 RE1/2 Chambers (One sector 60o) 6 Link Boards available

  12. Mass production gas gaps Korea full steam Assembly RE 1 ramped up @ ISR lab and has reached 5 chambers per week The final RE 1/2 RPC has been mated to ME 1/2 RE1/3 installation exercise performed Preparation for magnet tests started Summary and Conclusions RE 1 production expects to meet the CMS master schedule for its installation and commissioning
