Compton photography is a crucial diagnostic technique that utilizes picosecond ultra-short pulse lasers to generate hard x rays (50-200 keV) for backlighting inertial confinement fusion capsules at stagnation time, providing fuel density distribution measurements. To enhance the signal-to-noise ratio of backlighting under limited picosecond laser energy conditions, an online hard x-ray detector with high detection efficiency and gating capability is required to mitigate interference from long-du
