0736104 Danon本研究的目的是开发一种新型的热中子探测器，其基础是将高中子截面材料与专门制造的多层太阳能电池型器件相耦合。检测器包括被两个或更多个太阳能电池型器件夹在中间的高横截面转换材料，例如B-10或Li-6。中子通过（n，α）反应在转换层中相互作用，并且高能α由太阳能电池型设备检测。该研究包括一种新的检测器设计，以提高检测效率显着。MEMS技术中使用的深反应离子蚀刻将用于制造垂直太阳能电池型中子探测器阵列，这将增加转换材料含量，从而显著提高探测效率。学生将接受核探测器开发领域的教育，包括辐射与物质的相互作用和固态探测器的制造。

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.
