论文摘要
氢化的无定形硅（A-SI：H）具有显着的辐射抗性特性，并且可以沉积在许多不同的底物上。 A-SI：基于H的粒子探测器自1980年代中期以平面P-I-N或Schottky二极管结构而建造。这些检测器的厚度范围为1至50微米。但是，由于与高耗尽电压和低电荷收集效率相关的高泄漏电流相关的S/N比较差，因此使用平面结构的MIP检测一直存在问题。与平面结构相比，3D检测器结构的使用可能有益于减少电极间距离并增加较大电荷产生的检测器的厚度。这样的检测器可用于将来的强子围栏壁的辐射抗性以及X射线成像。此外，可以利用A-SI：H沉积在柔性材料上（例如Kapton）的可能性，以构建柔性和薄的光束通量测量探测器和X射线点测量器。
Hydrogenated amorphous silicon (a-Si:H) has remarkable radiation resistance properties and can be deposited on a lot of different substrates. A-Si:H based particle detectors have been built since mid 1980s as planar p-i-n or Schottky diode structures; the thickness of these detectors ranged from 1 to 50 micron. However MIP detection using planar structures has always been problematic due to the poor S/N ratio related to the high leakage current at high depletion voltage and the low charge collection efficiency. The usage of 3D detector architecture can be beneficial for the possibility to reduce inter-electrode distance and increase the thickness of the detector for larger charge generation compared to planar structures. Such a detector can be used for future hadron colliders for its radiation resistance and also for X-ray imaging. Furthermore the possibility of a-Si:H deposition on flexible materials (like kapton) can be exploited to build flexible and thin beam flux measurement detectors and x-ray dosimeters.
