“Complete the LHC Phase 1 Upgrades….” is how the first project-specific and concrete recommendation (Recommendation 10) of the 2014 Report of the Particle Physics Project Prioritization Panel (P5), “Building for Discovery,” starts. This short phrase has been the mission statement for U.S. CMS scientists from Fermilab and around 30 U.S. institutes for the last six years. On May 1, with the successful outcome of the Department of Energy Critical Decision 4 review, the project has been completed.

Cosmic rays are with us all the time, but they are a pain. This article outlines some of the techniques that are used at Fermilab to remove cosmic rays from experimental data.
