The COMPASS Setup for Physics with Hadron Beams

Understand

The main characteristics of the COMPASS experimental setup for physics with hadron beams are described.

• This setup was designed to perform exclusive measurements of processes with several charged and/or neutral particles in the final state.
• Making use of a large part of the apparatus that was previously built for spin structure studies with a muon beam, it also features a new target system as well as new or upgraded detectors.
• The hadron setup is able to operate at the high incident hadron flux available at CERN.
