Fabrication Techniques Used in the Construction of a High Resolution X-Ray Framing Camera

摘要

A high resolution x-ray framing camera (HRXFC) has been developed for use as a diagnostic tool for laser fusion experiments that is capable of recording a two-dimensional radiographic ''snapshot'' of an imploding fusion target with a shutter speed of <100 ps. Recent tests of a complete prototype instrument have demonstrated frame durations as short as 40 ps FWHM. The HRXFC is based on a gated 15-ohm strip transmission line. Into this stripline are imbedded various elements, both active and inactive, that must perform their respective functions while having a negligible impact on the electrical characteristics of the transmission line. A discussion of the theory of operation of the HRXFC is presented along with an introduction to the elements of the stripline and their functions. This is followed by a discussion of the special techiques used to fabricate the instrument. 10 figs. (ERA citation 13:006244)
