Abstract
One method of pulse pressure loading of material or plasma is axisymmetric compression using a convergent cylindrical detonation wave. Such a wave is often formed by multipoint initiation and has a number of specific features that may affect the properties of the objects under study. To solve specific problems, it is proposed to use an explosive laboratory setup based on a converging cylindrical detonation wave with 12-48 initiation points. The TNT equivalent of the charge is less than 1 kg. The main method of research is process visualization using a domestic high-speed Nanogeit camera with a nanosecond time resolution. The structure and velocity of the converging detonation wave along the radius were determined. It is shown that for a charge of limited thickness, the curvature of the detonation wave front for various explosives depends only on the distance to the initiation point.
