Studies of energy transfer to the surface of the material were carried out for various loading of plasma and magnitude of the external magnetic field.Calorimetry, optical emission spectroscopy, and high-speed imaging were used to determine the characteristics of PPV. When perpendicular to the plasma deposition, it was shown that a transient plasma layer is formed before the surface by stopping the main part of the plasma stream, even for sufficiently small plasma loads that do not cause the surface of the material to melt. The plasma density in the surface layer is much higher than in the stream.This results in a shielding effect to transfer energy to the surface. The shielding effect due to the formation of a dense plasma layer in front of the surface has a beneficial effect on increasing the life of the irradiated material and is important for reducing erosion of components during a large number of repeated ELMs.   Product Description popup.authors Eliseev Dmitry V AKSYNOV Nikolay M BIRKA Oleg Vl VOLKOVA Yulia Ye HERASHCHENKO Stanislav Se KOZACHOK Alexander St Krupnik Lyudmila Ivanivna KULIK Mykola V LADIGINA Marina Se MARCHENKO Anna K MAKHLAY Vadim A.
