“…Almost all current ion therapy accelerators use a linac to accelerate ions before injection, although some facilities (in China) opt for a cyclotron [43]. Future pre-accelerators may need to transmit larger currents and reach higher energies to avoid space-charge effects in high intensity beams, such as those required for FLASH therapy [39].…”

Cancer therapy using protons and heavier ions such as carbon has demonstrated advantages over other radiotherapy treatments. To bring about the next generation of clinical facilities, the requirements are likely to reduce the footprint, obtain beam intensities above 1 × 10 10 particles per spill, and achieve faster extraction for more rapid, flexible treatment. This review follows the technical development of ion therapy, discussing how machine parameters have evolved, as well as trends emerging in technologies for novel treatments such as FLASH. To conclude, the future prospects of ion therapy accelerators are evaluated.

“…1 In contrast with conventional photon therapy, the significant advantage of carbon-ion beams is the existence of Bragg peak, which can result in a precise conformal dose deposition to the desired volume while sparing the surrounding tissues as much as possible. 2 On the basis of the technical and clinical research on carbon-ion therapy at the Heavy Ion Research Facility (HIRF) in Lanzhou, China, 3 a commercial medical accelerator with better performance than the HIRF has been designed and built independently by the Institute of Modern Physics (IMP) in Wuwei, Gansu Province, China, ie, the heavy-ion medical machine (HIMM). The entire facility mainly consists of two electron cyclotron resonance (ECR) ion sources (the second source is a backup), a cyclotron injector, a synchrotron, and three high-energy beam-transport lines that deliver the accelerated carbon ions into two treatment rooms.…”

Purpose: The heavy-ion medical machine (HIMM), which is the first commercial medical accelerator designed and built independently by the institute of modern physics (IMP) in Wuwei, Gansu Province, China, had officially completed clinical trials at the time of this article's writing. Three types of detector systems were developed based on the ionization-chamber principle to monitor the beam parameters during treatment in real time, quickly verify the beam performance during a routine checkup, and ensure patient safety. Methods and materials: The above-mentioned detector systems were used for beam monitoring and quality assurance in the treatment system. The beam-monitoring system is composed of three integral ionization chambers (ICs) and two multistrip ionization chambers (MSICs) as a redundant design. The irradiation dose, beam position, and homogeneity of a lateral profile are monitored online by the beammonitoring system, and safety interlocks are established to keep the test results under the predefined tolerance limitation. The quality-assurance equipment was composed of one MSIC and one IC stack. The IC stack was used for energy verification. Results: The off-axis response of ICs is within a tolerance of 2%, and the dose interlock system (DIS) response time is less than 7 ms during the treatment process. The positioning resolution of MSICs reached 73 µm. The IC stack can verify the beam range within one spill and the measurement resolution is less than 0.2 mm. Conclusions: The beam-monitoring system (BMS) and quality-assurance equipment (QAE) have been installed and run successfully within HIMM for two years and are associated with the HIMM treatment system to deliver the right dose to the correct position precisely. Furthermore, the daily QA task is simplified by it. Above all, the system has passed the performance test of the China Food and Drug Administration (CFDA).
