COMPRESSION AND HEATING OF SPHERICAL FUSION-TARGETS BY INDIRECT (X-RAY) DRIVE ON THE ISKRA-5 FACILITY

Experiments have been carried out using the Iskra-5 facility in order to study the behavior of xray targets in response to a highly symmetri c x-ray field. Results are presented of experiments using targets in t he form of a spherical copper hohlraum coated with gold on the inside, with six laser entrance holes and a glass microtarget filled with DT gas located at the center. In some experiments the central capsule was coated with a plastic ablator layer of varying thickness. An analysis of the experimental results showed that on the whole, they are satisf actorily described by spherically symmetric gasdynamic calculations. ( C) 1998 American Institute of Physics.
