Development of the BHx Streak Tube: a high-throughput, high-resolution streak camera at the Laboratory for Laser Energetics

A new streak tube design suitable for high-throughput, high resolution X-ray spectroscopy is being developed at the Laboratory for Laser Energetics. It is designed to provide 70% internal photoelectron throughput with a flat, 25mm-long photocathode region, and a centered focus of 10 microns in the imaging direction and 40 microns in the swept direction onto a flat detector. We present data from electrostatic, UV-based optimization and characterization, comparisons to expectations from modeling, X-ray photocathode development, and progress towards dynamic testing.
