大面积雪崩光电二极管探测稀有气体闪烁光
Detection of Noble Gas Scintillation Light with Large Area Avalanche Photodiodes (LAAPDs)
摘要：
用大面积雪崩光电二极管（LAAPD）对Ar、Kr和Ar气中的闪烁光进行了一系列系统的测量。绝对量子效率的推导。Kr和Kr的值与制造商给出的值一致。对于第一次，我们表明，氩闪烁（128 nm）可以检测到量子效率超过40%。低压氩气显示出发射大量的非紫外线辐射。在此压力下，在氩气中产生非UV光子的平均能量消耗被测量为低于378 eV。
英文摘要：
Large Area Avalanche Photodiodes (LAAPDs) were used for a series of systematic measurements of the scintillation light in Ar, Kr, and Xe gas. Absolute quantum efficiencies are derived. Values for Xe and Kr are consistent with those given by the manufacturer. For the first time we show that argon scintillation (128 nm) can be detected at a quantum efficiency above 40%. Low-pressure argon gas is shown to emit significant amounts of non-UV radiation. The average energy expenditure for the creation of non-UV photons in argon gas at this pressure is measured to be below 378 eV.
