THEORY AND DESIGN OF A RACE-TRACK MICROTRON WITH APPLICATION TO THE GENERATION OF MILIIMETER WAVES

摘要

The race-track microtron treated is a four-sector design with homogeneous magnetic fields in the sectors. Synchronism and phase stability are investigated for an. energy gain that is variable from 0.5 to 1.0 MeV. Stability of betatron oscillations is examined using the "hard-edge" approximation for the shape of the magnetic field.nThe design of a race-track microtron is described, whose basic feature is its adaptability to different pole-piece arrangements.nBeam bunching in a microtron permits its application to the generation of millimeter and submillimeter waves. The mechanism causing beam bunching is investigated theoretically. Generation of 8 mm waves using the beam of a conventional microtron is described.
