12. Summary and Conclusions
Mass production gas gaps Korea full steam
Assembly RE 1 ramped 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
