Abstract:

Research was continued on the use of fast cyclotron waves to produce frequency multiplication in an output coupler. An attempt was made to improve the performance of the multiplier by increasing the perveance of the electron beam. The Heil electron gun has shown good characteristics in high perveance operation, so a standard Heil gun with a .010 in. anode aperture was placed in a magnetic shield. The performance of this gun was encouraging, as a beam current of 7.5 milliamperes was obtained at 350 volts. This is an increase of 2.8 times in beam conductance, which should increase the output power by the same factor, and the overall conversion efficiency should increase approximately by a factor of 8.
