Heavy ion therapy is the most advanced and effective method of radiotherapy. Because it has the advantage that it has minimal damage to surrounding healthy tissue and the greatest cancer celling killing effect. The relationship between heavy ion Bragg peak and beam energy requires the accelerator to switch the beam between different energy. The PXI RF control system plays an important role in Heavy Ion Medical Machine(HIMM). It can automatically change the waveform files according to the optical event. The system is mainly consisted by three FPGA cards, based on PXI bus, and mainly use the technology such as SOPC, DSP and so on. The PXI RF control system for HIMM has been tested through a long-term stability experiments, the system meets the proposed requirements.

Abstract: Heavy ion therapy is the most advanced and effective method of radiotherapy. Because it has the advantage that it has minimal damage to surrounding healthy tissue and the greatest cancer celling killing effect. The relationship between heavy ion Bragg peak and beam energy requires the accelerator to switch the beam between different energy. The PXI RF control system plays an important role in Heavy Ion Medical Machine(HIMM). It can automatically change the waveform files according to the optical event. The system is mainly consisted by three FPGA cards, based on PXI bus, and mainly use the technology such as SOPC, DSP and so on. The PXI RF control system for HIMM has been tested through a long-term stability experiments, the system meets the proposed requirements.
