PROSCAN CONTROL SYSTEM STATUS REPORT

The 250MeV compact cyclotron delivered by ACCEL (Germany) has been installed at PSI and is now in its commissioning phase. The cyclotron, COMET, will provide beam for the PSI proton therapy project PROSCAN. The Control system for this facility comprises three control systems: the COMET control system as provided by the supplier ACCEL, the Machine Control system (MCS) and the user control system (UCS) for each user area. The MCS is basically a copy of the control system used at the High Intensity Proton Facility at PSI , with some additional components required for a proper operation of the medical facility. In particular we will describe the mechanisms used for the interfacing of the UCS through a Beam Allocator System (BALL). We will also report on the progress in development and installation of the hardware and software as well as some first results of the operation of the facility.
