Energy-Resolved Soft X-Ray Framing Camera

A novel energy-resolved four-frame x-ray framing camera was developed for Qiang-guang I high power krypton gas-puff Z-pinch generator. The camera consisted of a pinhole array, two kinds of filters, a micro-channel plate (MCP) image intensifier, and a charge coupled device (CCD) camera. There are four microstrips on the input surface of the MCP. Two images are formed on each microstrip by two pinholes, one is filtered by 2 mum (micron) aluminized mylar and sensitive to 150 - 300 eV photons and those above 400 eV, another is filtered by 1 mum (micron) mylar plus 0.25 mum (micron) aluminum and sensitive to photons greater than 300 eV. Finally, the experimental results are discussed.
