Closer look at Li$_{6}$Gd(BO$_{3}$)$_{3}$:Ce capture-gated detectors for neutron spectrometry

Lithium gadolinium borate (LGB) capture-gated neutron detectors have good neutron detection efficiency and gamma ray rejection. We study them for use in neutron spectrometry using our in-house time of flight apparatus. Described here are several recent improvements to the apparatus along with some preliminary results.
