The control room. The accelerator as a whole, that is the source, the cyclotrons, and the beam guidance and diagnostic components, is a ?controlled from a control room known as the CCP: the Central Control Station (PCP in French). Between 3 and 10 operators adjust all of the parameters (approximately 2000) involved in the beam transport line, and monitor each experimental room and accelerator component, paying particular attention to those aspects related to radioprotection and safety.
