An intensified/shuttered cooled CCD camera for dynamic proton radiography
- and others
An intensified/shuttered cooled PC-based CCD camera system was designed and successfully fielded on proton radiography experiments at the Los Alamos National Laboratory LANSCE facility using 800-MeV protons. The four camera detector system used front-illuminated full-frame CCD arrays (two 1,024 x 1,024 pixels and two 512 x 512 pixels) fiber optically coupled to either 25-mm diameter planar diode or microchannel plate image intensifiers which provided optical shuttering for time resolved imaging of shock propagation in high explosives. The intensifiers also provided wavelength shifting and optical gain. Typical sequences consisting of four images corresponding to consecutive exposures of about 500 ns duration for 40-ns proton burst images (from a fast scintillating fiber array) separated by approximately 1 microsecond were taken during the radiography experiments. Camera design goals and measured performance characteristics including resolution, dynamic range, responsivity, system detection quantum efficiency (DQE), and signal-to-noise will be discussed.
