Theoretical and Experimental Investigation of Electron Beam Acceleration and Sub-Millimeter Wave Generation
Abstract
Four separate processes for electron beam acceleration and sub-millimeter wave generation have been studied. (1) We have extended our concept that harmonic gyro-TWT amplifiers can stably generate substantially higher power than at the fundamental cyclotron frequency by designing a third harmonic amplifier that is predicted to generate 2 MW with good stability and gain characteristics. (2) A three-cavity TE(0n) gyroklystron circuit, which is predicted to efficiently generate a peak power of 250 kW with high amplifier performance, has been received from the machinist. (3) The first high energy photoelectrons have been produced in the X-band rf gun. (4) In addition, the previous sixth-harmonic gyrofrequency multiplier that produced 3 kW with 5% efficiency has been upgraded so that it will emit its design value of 150 kW with 30% efficiency.
