Prototype cassettes mark key step toward new CMS high-granularity calorimeter
Phys.org, Janauary 29, 2026
CMS scientists recently formed the first prototype “cassette” for the new endcap calorimeters which will be the largest silicon-based detectors ever built when complete. This technology will increase in the number of particles that the HL-LHC will deliver and result in 4 to 5 times more simultaneous particle collisions than occur with the existing LHC.
