Beam diagnostic control system for shallow-seated tumor therapy terminal at HIRFL

Beam diagnositic control system for the heavy-ion cancer therapy project at the Heavy Ion Research Facility in Lanzhou(HIRFL) has been designed and constructed in the Institute of Modern Physics, Chinese Academy of Sciences. The system was developed on the basis of the PXI bus technology and LabVIEW, including beam intensity monitoring, radiation dose monitoring, and monitoring of scanning magnets’ power supplies. System tests and clinical operations show that this control system could meet basic requirements of the heavy-ion cancer therapy, such as radiation dose control and safety protection.
