Beam allocation apparatus and beam allocation method for medical particle accelerators
First Claim
1. Beam allocation apparatus for medical particle accelerators, the particle accelerator having at least one acceleration region, a transport path and deflection components, by way of which a plurality of treatment rooms, each having a control room, are supplied with a particle beam comprising ion packets,wherein the beam allocation apparatus has an arbitration unit having switching logic, monitoring unit and sequence control, which is in electrical communication, by way of signal lines, with a spill abort system which has at least two rapid spill abort elements in the acceleration region and/or in the beam guidance common to all the irradiation positions, the beam allocation apparatus providing direct access from the control room of the irradiation-active treatment room for aborting the particle beam within micro-seconds in the event of danger.

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.

16. Beam allocation method for medical particle accelerators, the particle accelerator having at least one acceleration region, a transport path and deflection components, by way of which a plurality of treatment rooms, each having a control room, are sequentially supplied with a particle beam comprising ion packets, the beam allocation method comprising the following method steps:
-
requesting reservation, by one of the control rooms, of particle beam sovereignty, especially reservation of direct access to a spill abort system of the acceleration region required by all the treatment rooms, for a planned irradiation duration; carrying out safety-relevant reservation of the spill abort system by an electronic switching logic of an arbitration unit; reporting of the completed reservation to each control room with permission for only control room to carry out beam aborting by means of the spill abort system; holding in a state of readiness, for the control rooms, a direct redundant signal path, which is independent of the arbitration unit,leading to the spill abort system of the acceleration system, the switching elements of the control rooms being connected in series, it being possible, in the event of simultaneous beam reservation requests from a plurality of control rooms, for the arbitration unit to decide which control room of an irradiation position can make the reservation and, it being possible, despite the loss of a reservation, for a spill abort to be initiated from each control room by way of the redundant signal path. - View Dependent Claims (17, 18, 19, 20, 21)
