High-dose rate detection system for gamma and X radiation using scattered gamma rays

Recent developments in the field of ultra-high intensity gamma sources have led to a renewed interest in detection of pulsed gamma radiation. This paper thus proposed a scintillation detector system based on scattered gamma rays by using the tungsten target. System design parameters were investigated with Monte Carlo simulation and verified by 60Co/137Cs radiation experiments. The results showed that the system can raise the upper limit of gamma intensity detection by 4-5 orders. Signal-to-noise ratio of the system was studied in the 60Co radiation experiments. These findings suggested that this system is a suitable alternative for future needs for ultra-intense gamma-ray measurements.
