Summary and Conclusions

• Mass production gas gaps Korea full steam
• Assembly RE 1 ramped up _at_ 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

RE 1 production expects to meet the CMS master
schedule for its installation and commissioning
