摘　　要：对国产低电阻微通道板(microchannel plate,MCP)在直流模式下的线性动态范围开展了详细研究。利用深紫外光源(低压汞灯)激发蒸镀有金阴极的MCP,获得较宽范围的输入电流,进而测试了与低阻MCP线性动态范围相关的各项参数,包括电阻、增益、传导电流以及最大最小输入电流等。结果表明:降低体电阻能够有效提高MCP的线性动态范围,其最大和最小输入电流之间跨越6个数量级;该低阻MCP在3种不同工作电压下,最大输出电流为传导电流的16%~19%,与国际上高输出技术MCP相比,性能相当,能够应用于相关领域。In this paper,a detailed study of the linear dynamic range of the domestic low-resistance microchannel plate(MCP)in DC mode is carried out.In the experiment,a deep ultraviolet light source(low-pressure mercury lamp)is used to excite the MCP with a gold film in order to obtain a wide range of input current,and then various parameters related to the linear dynamic range of the low-resistance MCP are tested.These parameters include resistance,gain,strip current,the maximum and minimum input current,etc.The results show that reducing the resistance can effectively improve the linear dynamic range of the MCP,and the maximum and minimum input current span over 6 orders of magnitude.The low-resistance MCP has a maximum output current of 16%to 19%of the strip current under three different operating voltages.It has comparable performance to the international high-output MCP technology and can be applied in related fields.
