Abstract

A new streak tube is in the preliminary design and review phase. Modeled after the newly designed microchannel-plate (MCP)-based x-ray-framing camera at the Lawrence Livermore National Laboratory (LLNL), this streak tube incorporates an MCP at the light input to amplify the signal before noise is introduced into the system. The signal-to-noise ratio of the streak tube is directly dependent on the gain setting of the MCP and can thus be greater than 1000:1. Temporal resolution will be about 30 ps, and the dynamic range should be greater than 500:1. Another tube of the same design, but employing a photocathode instead of the photocathode/MCP combination, has been studied briefly. With some minor modifications, it should be possible to achieve a dynamic range of about 20 with this version of the design, and to reduce the magnification to about 1 and improve the time response to 150 fs.
