摘要
详细报道了新研制的紫外多阳极微通道阵列光电倍增管。该器件采用了叠合式阵列阳极 (12 8× 12 8)、端窗式“日盲”紫外光电阴极 (碲铷RbTe)、高增益的Z型微通道板组件、近贴聚焦结构等先进技术。器件的主要性能参数为 :阴极发射灵敏度 18mA/W ,增益 2× 10 6,暗电流 0 5nA ,时间响应 0 3ns,单光子计数率 2× 10 5s-1。
The ultraviolet multi anode microchannel array (MAMA) photomultiplier has been successfully developed.Various advanced technologies,including an anode array with 128×128 pixels,head on “solar blind” ultraviolet photocathode made of RbTe film,Z type microchannel plates and the proximity focusing technique,were employed in the MAMA device.Major specifications of the device are as follows:cathode radiant sensitivity is 18 mA/W;current gain is 2×10 6;dark current is 0 5 nA;pulse rise time is 0 3 ns;single photon counting rate is 2×10 5 s -1 .
