采用激光驱动-中子源对EJ232Q、BC422Q和EJ410三个闪烁体进行了飞行时间校准。三个塑料闪烁体探测器使用伽马不敏感气泡探测器光谱仪进行校准，这些光谱仪在从亚MeV到20 MeV的广泛中子能量范围内进行绝对校准。图中显示了由探测器同时获得的一组典型数据，测量了由千瓦激光照射薄箔发出的中子谱。
Calibration of three scintillators (EJ232Q, BC422Q, and EJ410) in a time-of-flight arrangement using a laser drive-neutron source is presented. The three plastic scintillator detectors were calibrated with gamma insensitive bubble detector spectrometers, which were absolutely calibrated over a wide range of neutron energies ranging from sub-MeV to 20 MeV. A typical set of data obtained simultaneously by the detectors is shown, measuring the neutron spectrum emitted from a petawatt laser irradiated thin foil.
