High‐speed gated x‐ray imagers (invited)

Single‐ and multiframe gated x‐ray images with time resolution as fast as 150 ps are described. These systems are based on the gating of microchannel plates in a stripline configuration. The gating voltage comes from the avalanche breakdown of a reverse biased p–n junction producing high‐power voltage pulses as short as 70 ps. Results from single‐ and four‐frame x‐ray cameras used on Nova are described.
