Annotation: The article is concerned with the results of theoretical and experimental investigations of operating modes of electron source with plasma emitter when discharge chamber elements are thermally intensively loaded. It is shown that the constant magnet of the discharge chamber is the most vulnerable to temperature influence. The peculiarities of electron source design when operated in the conditions of intensive influence of a thermal load are described. The application of the developed source to technology of superconducting materials creation under program ITER is given in the article.

Keywords: electron source with plasma emitter, constant magnet, thermal load
