论文摘要
UHDPULSE-使用具有超高脉冲剂量率的光束进行晚期放射疗法的计量学是一个欧洲项目，旨在制定新型的剂量测定标准，并改善现有的标准，用于闪光灯放疗，非常高的能量电子放射疗法和激光驱动的医疗加速器。在该项目的范围内，使用热发光（TL）和光刺激的发光（OSL）检测器来测量杂散辐射场。使用常规脉冲颗粒梁进行的实验可以表征已知且可控的辐射场中的剂量计。反过来，这允许开发模型并预测其在复杂的辐射场中的行为，例如激光驱动和闪光设施的行为。 TL和OSL探测器在捷克共和国布拉格的Microtron MT25电子加速器上进行了辐照。 Gafchromictm膜和塑料核轨道探测器分别用于研究束轮廓和中子背景。比较了微龙MT25的脉冲混合辐射场的不同检测器的响应相互比较并在本文中介绍。
UHDpulse - Metrology for Advanced Radiotherapy using beams with Ultra-High Pulse Dose Rates is a European project aimed at developing novel dosimetry standards, as well as improving existing ones, for FLASH radiotherapy, very high energy electrons radiotherapy, and laser-driven medical accelerators. Within the scope of this project, Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) detectors are used to measure stray radiation fields. Experiments performed with conventional pulsed particle-beams allow to characterize the dosimeters in known and controllable radiation fields. In turn, this allows to develop models and predict their behavior in complex radiation fields, such as those at laser-driven and FLASH facilities. TL and OSL detectors were irradiated at the Microtron MT25 electron accelerator in Prague, Czech Republic. GAFChromicTM films and plastic nuclear track detectors were used to study the beam profile and the neutron background respectively. The responses of the different detector to the pulsed mixed radiation fields of the Microtron MT25 are compared among each other and presented in this paper.
