The Development of the Graphite Barrel of the Coaxial Magnetoplasma Accelerator

The plasma accelerators are widely used for some powder and bulk (coatings) materials synthesis. Some metastable or high temperatures polymorphs require some special conditions for crystallization, for example ultra-high cooling rate. One of the possible ways to obtain these materials is the synthesis in a high speed plasma jet generating by a high current pulsed power plasma accelerator. The paper presents the results of experimental research concerning the development of a graphite barrel design of a high-current coaxial magnetoplasma accelerator. The developed design allows generating high-speed carbon electric discharge plasma jets with a pulse supply energy over 30 kJ by electrical power of about 140 MW.
