A gated, four-frame pinhole camera with quantitative image acquisition

A gated, multiframe microchannel plate soft X-ray sensor with quantitative acquisition has been developed. The system is composed of an image acquisit ion system and a gated pinhole camera capable of taking four successive fra mes at a time resolution of similar to 220 ps. The response of the system h as been quantitatively investigated. To perform a quantitative evaluation o f the captured X-ray images, the image acquisition and measurement of the p hosphor current are executed simultaneously in the experiment. The system h as been examined using a plasma X-ray source generated by a plasma focus de vice with an additional gas puff. The compression and bifurcation process o f plasma hot spots in a neon puffed experiment has been successfully record ed. Quantitative analysis of the images indicates that an order of 10(16) p hotons/(s.mm(2).mrad(2)) emissions originate from the plasma in a soft X-ra y region 6-14 Angstrom.
