An X-ray pinhole camera has also been fielded to measure the spatial distribution of X-ray production. Initially a phosphor scintillator screen coupled with a visible-light camera was used to detect X-ray photons with single frames per shot. We observe localized emission from edges of in-vessel metal components, in addition to more diffuse emission presumed to be from the pinch plasma. A direct-detection X-ray image sensor, capable of 5 MHz frame rate for hundreds of frames, will be evaluated. The high efficiency of the sensor is expected to provide adequate signal-to-noise ratio at high temporal and spatial resolution.
