ECR plasma in a high power millimeter-wave beam, 1

Using a high power millimeter-wave beam of Gyrotron, ECR plasma production and heating are experimentally studied. Characteristic features of 60 GHz Gyrotron used in the experiment are described with the program plan on the efficient usage of this millimeter-wave beam to high temperature plasma production and surface heating of materials. Preliminary experimental results in Ar gas are reported indicating a high density plasma production with nsub(e)asymptotically equals 1013cm-3 and with a strong X-ray radiation at a pressure over 1x10-1 Pa.
