论文摘要
HASPIDE（氢化的无定形硅像素探测器）项目旨在开发在柔性底物（主要是聚元素）上用于光束监测，中子检测和空间应用的薄氢无定形硅（A-SI：H）探测器。由于A-SI：H是具有出色辐射硬度的材料，因此可以在辐射刺激性的环境中大多欣赏到上述应用的好处。此外，将该材料沉积在柔性底物（PI），聚乙二醇苯二甲酸酯（PEN）或聚乙二醇三甲酸酯（PET）等柔性底物上的可能性促进了这些探测器在医疗剂量测定，束横梁磁通量和束谱测量中的使用。特别有趣的是，当直接放置在光束线上真空对空地分离界面的法兰以及其他薄薄的自动辐射检测器的应用中，它的用途。在本文中，将描述Haspide项目，并将报告一些有关PI和玻璃基板的初步结果。
The HASPIDE (Hydrogenated Amorphous Silicon PIxels DEtectors) project aims at the development of thin hydrogenated amorphous silicon (a-Si:H) detectors on flexible substrates (mostly Polyimide) for beam monitoring, neutron detection and space applications. Since a-Si:H is a material with superior radiation hardness, the benefit for the above-mentioned applications can be appreciated mostly in radiation harsh environments. Furthermore, the possibility to deposit this material on flexible substrates like Polyimide (PI), polyethylene naphthalate (PEN) or polyethylene terephthalate (PET) facilitates the usage of these detectors in medical dosimetry, beam flux and beam profile measurements. Particularly interesting is its use when positioned directly on the flange of the vacuum-to-air separation interface in a beam line, as well as other applications where a thin self-standing radiation flux detector is envisaged. In this paper, the HASPIDE project will be described and some preliminary results on PI and glass substrates will be reported.
