长寿命微通道板是一种新型的微通道板。它的玻璃结构是按特殊配方制造的,适合于作高温处理。它具有优良的电特性。其特点是:1.寿命长——带电流和增益的电稳定性明显提高;2.与标准微通道板相比具有更优良的暗噪声;3.比标准微通道板回收利用率更高;4.可在高温下真空烘烤,使管子取得最佳除气效果和更好的性能。内部微通道板寿命试验表明,在三个独立的试验周期中,长寿命微通道板比我们的标准微通道板更稳定。美国陆军夜视实验室已鉴定了两只用长寿命微通道板组装的管子。结论是:与标准微通道板的管子相比,此种微通道板的电子增益、带电流和暗噪声都好。
Long-life microchannel plate is a new type of microchannel plate. Its glass structure is made in a special formulation suitable for high temperature treatment. It has excellent electrical characteristics. Its characteristics are: 1. Long life - electrical stability with current and gain significantly improved; 2. Compared with the standard microchannel plate has better dark noise; 3. More than the standard microchannel plate recycling rate higher; 4. Can be vacuum baked at high temperature, so that the best degassing effect and better performance of the tube. Internal microchannel plate life tests showed that the long-lived microchannel plates were more stable than our standard microchannel plates in three separate test cycles. The US Army Night Vision Laboratory has identified two tubes assembled with long-lived microchannel plates. The conclusion is: Compared with the standard microchannel plate tube, the microchannel plate electronic gain, with current and dark noise are good.
