ARI-SA: A NOVEL SOLID-STATE SELF POWERED NEUTRON DETECTOR

这项研究的目标是开发一种新型的热中子探测器，该探测器基于高中子截面材料与专门制造的多层太阳能电池型器件的耦合。该探测器包括夹有两个或更多个太阳能电池型器件的高截面转换材料，例如B-10或Li-6。转换层中的中子通过(n，α)反应相互作用，高能α由太阳能电池型器件探测到。本研究设计了一种新颖的检测器，以显著提高检测效率。MEMS技术中使用的深反应离子刻蚀技术将用于制造垂直太阳能电池型中子探测器阵列，这将增加转换材料的含量，从而显着提高探测效率。学生将在核探测器开发领域接受教育，包括与物质的辐射相互作用和固态探测器制造。

0736104DanonThe objective of this research is to develop a new type of thermal neutron detector based on coupling a high neutron cross-section material with specially fabricated solar cell type devices that are multi-layered. The detector includes a high cross section conversion material such as B-10 or Li-6 sandwiched by two or more solar cell type devices. The neutrons interact in the conversion layer by the (n,alpha) reaction and the energetic alpha is detected by the solar cell type devices. The research includes a novel detector design to improve the detection efficiency significantly. Deep reactive ion etching that is used in MEMS technology will be used to fabricate an array of vertical solar-cell type neutron detectors that will increase the conversion material content and thus significantly increase the detection efficiency. Students will be educated in the area of nuclear detector development that includes radiation interaction with matter and solid- state detector fabrication.
