Abstract
The invention relates to a beam allocation apparatus (21) for medical particle accelerators and also to a beam allocation method. This beam allocation apparatus (21) should manage a plurality of control rooms (8-12) for different treatment rooms and for quality assurance rooms and control rooms for the particle accelerator (1) and co-ordinate the assignment of beam sovereignty. For the purpose, the beam allocation apparatus (21) has an arbitration unit (26) having switching logic (27) and monitoring unit (28) and also a sequence control (29). The latter are provided, by way of signal lines (30), with a spill abort system (31) for aborting ion beam irradiation within micro-seconds. For the purpose, the spill abort system (31) has at least one spill abort magnet (32). For the purpose, the beam allocation apparatus (21) provides direct access from one of the control room (8-12) of the irradiation-active treatment room for aborting the particle beam within micro-seconds.
