Response Of A Lead-Free Borosilicate-Glass Microchannel Plate To 14-Mev Neutrons And Gamma-Rays

In microchannel plate applications, such as in space telescopes, night-vision devices, or time-of-flight particle detection, reducing the sensitivity to signals from background sources, such as gamma-rays, is beneficial for the system design and performance. The response of a single-stage lead-free borosilicate-glass microchannel plate to 14-MeV neutrons and gamma-rays produced via (n, gamma) reactions in surrounding structures was investigated at OMEGA. The average efficiency values for secondary electron production were found to be (5.1 +/- 0.7) x 10(-3) for 14-MeV neutrons and (4.9 +/- 1.1) x 10(-3) for 1.5 -MeV gamma-rays.
