Abstract :
An absorption investigation of a number of diamond disks for output windows of megawatt gyrotrons in the range of frequencies 50-180 GHz is carried out. It was found out that after high temperature brazing, the disks´ surfaces obtain an additional number of free charge carriers in a thin, <\n\n\t\t
