论文摘要
闪光辐射疗法要求将快速爆发的颗粒溢出，剂量递送时间毫秒级。这些要求与在CERN研究的基本物理实验请求重叠，尽管能量尺度非常不同。在这一贡献中，通过控制第三级谐振剂和射频相位位移加速度来探索一种从同步基因提取毫秒爆发的方案。该计划将在现有的医疗和实验同步器设施中实施。使用CERN质子同步子的模型，模拟了单生和多胚萃取。结果表明，总束强度的80-90％以40-60毫秒的单次爆发提取。这对应于典型的医疗同步器中的〜10毫秒爆发，即质子离子医疗机器研究中概述的爆发。用优化的机器参数模拟了一组30 ms的连续30 ms的突发。
FLASH radiation therapy calls for the delivery of fast bursted spills of particles with dose delivery times of the order of milliseconds. The requirements overlap with fundamental physics experimental requests that are being studied at CERN, albeit at very different energy scales. In this contribution, a scheme for extracting millisecond bursts from synchrotrons is explored by controlling a third-integer resonant and chromatic extraction with RF phase displacement acceleration. The scheme would be implementable in existing medical and experimental synchrotron facilities. Using a model of the CERN Proton Synchrotron, both single-burst and multi-burst extractions are simulated. Results show that 80 - 90% of the total beam intensity is extracted in a single burst of 40 - 60 ms. This would correspond to a ~10 ms burst in a typical medical synchrotron, namely the one outlined in the Proton Ion Medical Machine Study. A set of 3 consecutive bursts of 30 ms was simulated in the Proton Synchrotron with optimised machine parameters.
