杜克大学高强度伽马源已经设计并测试了一种新型的光子通量监测器。五闪体桨系统探测光电、康普顿和配对生产过程中的反冲电子和正电子。它被设计成对增益和探测器阈值的变化不敏感，并且可用于5 MeV以上的光子能量。它已经用NaI探测器的直接计数进行了校准，并且它的效率已经被GEANT4模拟很好地描述。
A novel photon flux monitor has been designed and tested for use at the Duke University High Intensity Gamma Source. The five-scintillator-paddle system detects recoil electrons and positrons from photoelectric, Compton and pair-production processes. It is designed to be insensitive to gain and detector threshold changes and is usable for photon energies above 5MeV. It has been calibrated using direct counting with a NaI detector, and its efficiency has been shown to be well described by a GEANT4 simulation.
