US-built carbon support tube arrives at CERN for the CMS experiment upgrade

Fermilab — A key milestone in the U.S.-funded upgrade to the CMS experiment was achieved with the successful delivery of a 5-meter-long carbon support tube to CERN. Designed and built at Purdue University, the tube will house new inner particle detectors for CMS, which is being prepared for the high-luminosity upgrade of the Large Hadron Collider. The CMS collaboration is composed of scientists from roughly 240 institutions spread across more than 50 countries. Purdue Physicist Andy Jung was one of those scientists.
