摘要
研究空间介质材料在60Co伽马射线辐照下,不同辐射剂量率对介质材料辐射诱导电导率产生过程中的作用,分析辐照下内部电荷产生、复合和流动机理,建立辐射诱导电导率测试方法,为航天器内带电效应防护设计研究提供依据。对比高能电子辐照和伽马射线辐照的不同,开展60Co伽马射线辐照条件下介质材料内部电荷产生、复合及流动机理分析,明确影响微小电流测量的因素,采用三电极法测量技术,测量介质材料在不同剂量率下辐射诱导电导率的变化趋势,通过公式拟合得到辐射诱导电导率参数Kp和(35)。试验获得60Co剂量率分别在10rad/s,30rad/s和50rad/s下,Kapton辐射诱导电导率分别为1.9×10-16Ω-1.cm-1、4.7×10-16Ω-1.cm-1和7.1×10-16Ω-1.cm-1,Teflon辐射诱导电导率分别为7.3×10-16Ω-1.cm-1、1.3×10-15Ω-1.cm-1和1.6×10-15Ω-1.cm-1,无辐照条件下测得的Kapton和Teflon的本征电导率分别为3.1×10-17Ω-1.cm-1和2.3×10-16Ω-1.cm-1。通过最小二乘法拟合得到Kapton的Kp=3.1×10-17Ω-1.cm-1.rad-1.s和(35)=0.8,Teflon的Kp=2.3×10-16Ω-1.cm-1.rad-1.s和(35)=0.5。空间介质材料辐射诱导电导率随辐照剂量的增加呈上升趋势,通过与国外测试数据比较,所测试验数据与国外数据符合性较好,从而验证了建立的星用材料辐射诱导电导率测试装置的有效性。
