Abstract

The absolute sensitivity of two soft x-ray stream camera transmission photocathodes was measured at λ = 0.266 μm. The photocathodes were mounted in a Lawrence Livermore National Laboratory soft x-ray streak camera and were compared in sensitivity to a more conventional UV photocathode. Measurements were performed with a 30-psec 0.266-μm pulse from a frequency-quadrupled glass laser. The study revealed photocathode substrate transmission at 0.266 μm, minimum UV energy density requirements, temporal response, and an estimate of streak camera dynamic range for UV exposure.
