摘要

本文主要研究了半绝缘(SI) InP: fe基粒子探测器，重点介绍了探测器体积的作用。制备了三种不同材料的有效接触面积为0.3 ~ 5.5 mm/sup 2/，基底长度分别为190、400和1830 /spl mu/m的探测器并进行了测试。得到的衰减体积范围为0.12 ~ 5.7 mm/sup 3/。在230 K温度下测试了探测器的检测性能。演示了使用/spl伽马/射线源(/sup 241/Am， /sup 57/Co)测试的电荷收集效率和能量分辨率。讨论了长基(>500 /spl mu/m)探测器在> 1kv电压下的测量问题，以及适用于太阳中微子探测的基于体硅InP的“大体积”辐射探测器的结构。

Electrical and detection performance of radiation detector based on bulk semi-insulating InP:Fe: role of detector volume

In this work study of bulk semi-insulating (SI) InP:Fe-based particle detectors with emphasise to the role of detector volume is presented. Detectors based on three various materials with active contact area between 0.3-5.5 mm/sup 2/ and various base length, 190, 400, and 1830 /spl mu/m were fabricated and tested. Obtained attenuation volume ranges between 0.12 and 5.7 mm/sup 3/. Detection performance of detectors was tested at temperature 230 K. Charge collection efficiency and energy resolution tested using /spl gamma/-ray sources (/sup 241/Am, /sup 57/Co) are demonstrated. Problems of measurement at voltages >1 kV necessary for detectors with long base (>500 /spl mu/m) and architecture of a "large volume" radiation detector based on bulk SI InP applicable in detection of solar neutrino are discussed.
