Abstract

Temporally and spectrally resolved x-ray emission is an important diagnostic tool for the study of target heating and compression induced by sub-nanosecond laser pulses. In this paper we describe the use of the Livermore 15 psec x-ray streak camera to record x-ray emissions in the 1-10 keV range. In particular, we report significant progress during the past year in defining the camera as a quantitative diagnostic instrument, and its implementation for multi-channel, time resolved K-edge filter measurements. Data will be presented which describe x-ray emission from a laser imploded 87 pm diameter glass shell. Channels centered at 2.6, 4.0 and 5.3 keV provide temporal information which we relate to the absorption and compression phases of laser heating. The relative spectral content is found to be in agreement with standard, time integrated measurements.
