Abstract:

The applied research effort will be directed toward the establishment of the feasibility of generating millimeter wave energy through the use of a fast cyclotron wave interaction which results in frequency multiplication. The frequency multiplier which is the subject of the current investigation utilizes the fast cyclotron wave on an electron beam which is focused by a magnetic field and subjected to transvere acceleration at a frequency near the cyclotron resonance of the focusing field. The fast wave appears in the form of transverse rotational electron motion of c nstant angular velocity corresponding to the electron cyclotron frequency of the magnetic focusing field. If the exciting field is tuned to the cyclotron frequency of the focusing field, the electrons will move in phase with the excitation voltage. An electron initially in an accelerating field will remain in an accelerating field, increasing its kinetic energy and thus its radius of rotation, since angular velocity must remain constant. Electrons initially in a decelerating phase of the field will continue to decelerate, giving up energy and decreasing their radii of rotation eventually moving to the axis of rotation near the center of the beam from which they can be moved only by an accelerating field.
