N2031光电倍增管 80mm/(3")/Head-on type/10-stage
N2031 PMT 80mm/(3")/Head-on type/10-stage
N2031光电倍增管主要应用于高能物理探测领域,具有量子效率高、背景脉冲比例低、时间响应快等优点。本产品采用Sb-K-Cs阴极作为光电阴极,该阴极对350~450nm波段的量子效率高;采用金属打拿极作为电子倍增系统,经过10级倍增后可以达到106电子增益。经过优化后采用紧凑的结构设计,因而具有优越的时间响应。产品性能可以按客户需求订做。
N2031 PMT mainly applies in high energy physics detecting fields. The PMT has the characteristics of high quantum efficiency, low background pulse ratio, fast time response, etc. Using Sb-K-Cs as photocathode, PMT enjoys very high quantum efficiency at 350~450nm. With metal dynode as electron amplifier, the gain could reach 106 after 10 level multiplication. Besides, it also enjoys superior temporal response thanks to compact structure. At present, We are in a position to supply custom-made PMT upon your special requirements.
