60 MeV质子位移损伤效应模拟试验装置及辐照试验应用
A 60 MeV proton displacement damage effect simulation facility and its application in radiation testing
摘要
Abstract
The 60 MeV Proton Radiation Effects Facility(PREF)delivers a monoenergetic proton beam continuously adjustable between 10 MeV and 60 MeV,characterized by excellent monochromaticity(energy spread＜2‰),high spatial uniformity(＞90%),and rapid energy switching(≤10 min).It is primarily designed to simulate displacement damage effects on spacecraft optoelectronic devices and payloads under space radiation conditions.Since its commissioning in September 2023,PREF has supported multiple irradiation experiments on radiation-hardened devices,high-sensitivity optoelectronic components,and new-generation solar cells.These tests have provided crucial technical validation for on-board CMOS image sensors and satellite power systems.Displacement damage experiments conducted using PREF revealed the degradation behavior of dark current and hot pixels in CMOS sensors under different proton fluences.The findings offer indispensable experimental support for radiation-hardening design and in-orbit reliability assessment of spacecraft systems.关键词
