The improved theory of Ohmic losses which takes into account effects of a field increase near edges of corrugations is developed for a coaxial gyrotron cavity with a corrugated inner conductor. It is shown that for the ITER relevant TE 3 4 ,1 9 coaxial gyrotron operating at the maximal output power (-2 MW) they do not lead to a notable increase of the total losses in the corrugated inner insert. However they can contribute substantially to the local density of losses near edges of corrugations especially in the shot pulse regimes when contribution of higher axial harmonics to the total field can be substantial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
