N2031光電倍增管 80mm/(3")/Head-on type/10-stage
N2031 PMT 80mm/(3")/Head-on type/10-stage
N2031光電倍增管主要應(yīng)用于高能物理探測領(lǐng)域，具有量子效率高,、背景脈沖比例低,、時間響應(yīng)快等優(yōu)點(diǎn)。本產(chǎn)品采用Sb-K-Cs陰極作為光電陰極,，該陰極對350~450nm波段的量子效率高；采用金屬打拿極作為電子倍增系統(tǒng),，經(jīng)過10級倍增后可以達(dá)到106電子增益,。經(jīng)過優(yōu)化后采用緊湊的結(jié)構(gòu)設(shè)計，因而具有*的時間響應(yīng),。產(chǎn)品性能可以按客戶需求訂做,。
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.
