We have fabricated and tested a zone plate coded imaging camera for use with high energy x rays and charged particles. The camera system has demonstrated a higher order resolution capability of 4 ..mu..m with 100 keV x rays and 9 ..mu..m with 6 MeV protons. The unique components of this zone plate shadow camera are its thick zone plate coded aperture and recording medium for protons. The coded aperture is a free-standing, 75 ..mu..m thick, gold micro-Fresnel zone plate with 30 ..mu..m minimum zone width. It was fabricated by extending reactive ion etching and gold microplating techniques to ''thick'' structures. The proton recording medium is CR-39, a polycarbonate plastic, which serves as a high resolution nuclear track detector highly sensitive to protons.
