Paper Abstract

Strong interest exists at the Lawrence Livermore National Laboratory in studying the physics of transient, high density, high temperature, hydrogen plasmas. Because sequenced imaging is a major part of the diagnostics of these plasmas a continuous effort is made to improve the components of our imaging system and their calibration and to review operating procedures and techniques. The major components of our transient data, optical imaging systems are gated microchannel plate intensifiers (MCPI), solid-state array cameras, and fiberoptic data acquisition systems. Gated MCPIs are currently used with our solid-state cameras to provide sub-nanosecond snapshots of an optical pulse from a radiation-to-light converter. Efforts are made (1) to characterize photocathode response, modulation transfer function, luminous gain, and gating speed of each MCPI during the gating period, and (2) to improve pertinent MCPI parameters such as extinction ratio, gate pulse shape, resolution, and uniformity. A review of our high-speed imaging systems and components and their developments and calibrations is also presented.
