测量的双光电子发射（DPE）的概率作为波长的函数的报告滨松R8778，R8520，和R11410 VUV敏感的光电倍增管（PMT）。在DPE中，单个光子撞击PMT光电阴极并产生两个光电子而不是单个光电子。发现导致DPE发射的检测到的光子的分数是入射光子波长的函数，并且在低于10250 nm时表现出自身。对于175 nm的氙闪烁波长，根据管和测量方法测得的DPE概率为18-24%。这种依赖于波长的单光子响应对当前和未来的液体氙探测器（如LUX，LZ，XENON 100/1 T，Panda-X和XMASS）的能量校准和光子计数具有影响。
Measurements of double photoelectron emission (DPE) probabilities as a function of wavelength are reported for Hamamatsu R8778, R8520, and R11410 VUV-sensitive photomultiplier tubes (PMTs). In DPE, a single photon strikes the PMT photocathode and produces two photoelectrons instead of a single one. It was found that the fraction of detected photons that result in DPE emission is a function of the incident photon wavelength, and manifests itself below ∼250 nm. For the xenon scintillation wavelength of 175 nm, a DPE probability of 18–24% was measured depending on the tube and measurement method. This wavelength-dependent single photon response has implications for the energy calibration and photon counting of current and future liquid xenon detectors such as LUX, LZ, XENON100/1T, Panda-X and XMASS.
