AI 中文摘要
Photo-HASPIDE实验旨在构建并测试一种间接a-Si:H（氢化非晶硅）光电探测器加闪烁体的柔性器件，用于检测和测量粒子通量（X射线、电子和质子）及剂量测量。该实验利用a-Si:H作为光电二极管材料，因其具有辐射硬度、光探测能力和机械柔韧性等显著特性。在探索了基于聚酰亚胺（PI）衬底上的a-Si:H器件进行直接辐射检测的HASPIDE实验后，此次旨在研究将这些器件与聚硅氧烷等柔性且耐辐射的闪烁体结合进行间接检测。间接探测器设计有望比直接检测方法对低辐射通量具有更高的响应度。间接a-Si:H探测器应由a-Si:H光电二极管读取的小尺寸（约5×5mm2）闪烁体晶体阵列组成。通过优化闪烁体和探测器厚度，期望在低最小可探测通量方面比直接检测方法有更好的性能。这种新探测器将应用于放射治疗或强子治疗中的体内剂量测定，因其预期的快速响应，也可用于FLASH治疗。另一个重要应用是在太阳物理学中，使用这些器件测量太阳高能粒子事件中的粒子通量。
英文摘要
The objective of the Photo-HASPIDE experiment is the construction and test of an indirect a-Si:H (Hydrogenated Amorphous Silicon) photo-detector plus scintillator device on a flexible substrate for the detection and measurement of particles fluxes (X-rays, electrons and protons) and for dosimetric measurements. The idea behind this experimental project lies in the utilization of Hydrogenated Amorphous Silicon (a-Si:H) as photodiode material; owing to its notable attributes of radiation hardness, light detection capability and mechanical flexibility. After the implementation of the HASPIDE experiment, which explored direct radiation detection using a-Si:H devices on a polyimide (PI) substrate, we aim to delve into indirect detection by employing these devices in conjunction with flexible and rad-hard scintillators like polysiloxane. The indirect detector design holds promise for improved responsiveness to low radiation fluxes compared to direct detection methods. The indirect a-Si:H detector should be composed of arrays of small (about 5 x 5 mm2) scintillator crystals read by a-Si:H photodiodes. Through optimization of the scintillator and detector thicknesses, we expect to achieve a better performance for low minimum detectable fluxes compared to direct detection methodologies. This new detector will find application in in-vivo dosimetry during radiotherapy or hadron-therapy and also, due to its expected fast response, in FLASH therapy. Another important application will be also in Solar Physics using these devices to measure particle fluxes in solar energetic particle events.
