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——通道的带电流和增益的电稳定性明显提高; 2.暗噪声优于标准微通道板; 3.比标准的微通道板更便于回收使用; 4.可在高温下真空烘烤,能使管子取得最佳的除气效果及更好的性能。室内微通道板电寿命试验表明,在三个独立的试验周期中,长寿命微通道板明显地比标准微通道板更稳定。美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、带电流和暗噪声都比它好。
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 - the channel with the current and gain of the electrical stability improved significantly; 2. Dark noise is better than the standard microchannel plate; 3. More than the standard microchannel plate easier to recycle; 4. Under high temperature vacuum baking, the tube can get the best degassing effect and better performance. Indoor microchannel plate life test showed that the long-lived microchannel plate was significantly more stable than the standard microchannel plate in three separate test cycles. The U.S. Army Night Vision Laboratory has identified two tubes assembled with long-lived microchannel plates and concluded that the microchannel plates have a lower electronic gain, current and dark noise than tubes of standard microchannel plates it is good.
