Tests of refractory and high-porous metals in plasma device at National Research University MPEI

The plasma device at the National Research University “MPEI” has been constructed within the scope of the National controlled fusion program to test materials for fusion reactors, namely, fusion neutron sources FNS, DEMO and the international fusion reactor ITER. The device is a plasma trap with a linear multicusp configuration of the magnetic field and stationary plasma discharge that provides high-power plasma thermal load on the samples under testing which are made of materials of the fusion reactor first wall. It is planned to develop a new technology for creating highly porous structure on the surfaces of refractory metals, including the so-called tungsten “fuzz” with diameters of pores and nanofibers of ∼50 nm, which is of considerable interest for nuclear, power engineering and biomedical technologies.
