Abstract
The possibility of detecting fast ions (protons and α particles) using an X-ray-sensitive streak camera with a CsI photocathode is demonstrated. The spatial resolution of the instrument is 70 μm, and its physical time resolution is 7 ps. The yield of secondary electrons from the photocathode irradiated with α particles is 8 electrons/particle. The instrument is able to detect single α particles and protons. A technique for the spatial and spectral measuring of fast ions emitted from laser thermonuclear targets has been developed on the basis of this instrument. The technique is used at the ISKRA-5 facility to study the interaction between high-intensity laser radiation and thermonuclear targets.
