For the last six years, the mission of U.S. CMS scientists has been, in a phrase, to complete the LHC Phase 1 Upgrades. On May 1, with the successful outcome of the DOE Critical Decision 4 review, the U.S. CMS group fulfilled that mission. We’re proud of all the work we’ve done to upgrade the CMS detector so it can handle the increased luminosity of the Large Hadron Collider.
