The PLM Plasma Device for Tests of Tungsten with Powerful Stationary Heat Plasma Loads

Abstract

The PLM plasma device for plasma testing of refractory metals and materials of a fusion reactor (like the fusion neutron source and DEMO) within the framework of the domestic fusion program and the ITER project was constructed at the National Research University Moscow Power Engineering Institute in 2017. The device is a linear trap with a multicusp magnetic confinement of plasma. At the facility, tests of tungsten and experiments are being carried out aimed at creating a technology for producing a highly porous surface structure of refractory metals such as tungsten and molybdenum, including those with a fuzzy surface structure with the size of elements of the structure up to 50 nm.
