  • Abstract
    Different treatments on the cathode surface are adopted to enhance the secondary electron emission(SEE)of the cathode in high-power continuous wave magnetron tubes, which show that SEE coefficient of the pure tungsten cathode sprayed sand for coarseness and coated W-Re5%wt film is higher than that of untreated pure tungsten cathode.
