Abstract

In laser fusion and related fields the interaction between the laser and the target material is followed by the emission of x rays. The time history of these x rays is experimentally recorded by streak cameras. The currently used streak cameras have physical limitations for the temporal and spatial resolution limit. This paper presents a novel concept for a streak camera where these limitations are relaxed. In the camera described the photoelectron is moving in parallel electric and magnetic fields. The proposed design parameters use moderate fields and give time resolution limits of a few picoseconds and no spatial dispersion in one dimension.
