High Efficiency Detectors for Time-of-Flight with High Energy Neutrons

摘要

Experience in achieving sub-nanosecond time resolution with neutrons about 100 MeV on a scintillation detector 15 x 15 x 100 cm viewed by a single phototube is discussed. Time compensation is accomplished by tilting the scintillator axis with respect to the neutron flight path as discussed previously. The interplay between the time compensation from the geometry of light collection and the electronic technique for picking off the time signal is described. (ERA citation 03:033640)
