Head Volodymyr Y. Moiseenko, Доктор фізико-математичних наук Registration Date 05-03-2021 Organization National Science Center "Kharkiv Institute of Physics and Technology" popup.description1 The main goal of the work is to develop technology for cleaning vacuum surfaces with plasma of high frequency discharges (HF) of different frequency bands in combination with DC discharge, which will have high efficiency and low level of physical spraying of the installation elements in the vacuum chamber. The aim of the work is also to improve the methods of RF plasma generation. The offered researches are directed on modernization of the existing diagnostics on the U-2M stelarator and adaptation of new diagnostics (such as ECE diagnostics, refractive diagnostics). The dependence of the main parameters of the plasma as well as its stability on the magnetic field, on the experimental conditions in particular on the plasma heating conditions will be investigated. popup.nrat_date 2024-12-09 Close
