CMS quartz fiber calorimeter

The CMS will be a general purpose detector for the Large Hadron Collider at CERN. Its quartz fiber calorimeter is designed to provide hermetic measurement of energy flow in the forward rapidity region. The calorimeter must operate under extremely hard radiation conditions and almost without maintenance. Several prototypes have been constructed and tested at the CERN high-energy beam. The cost effective technology of manufacturing of fine sampling absorber modules has been developed.
