Cold tests of quasi-optical gyrotron resonators
Abstract
Cold tests are performed on a number of quasi-optical gyrotron resonators at 94 and 120 GHz to determine the variation of cavity Q with mirror separation. The separation between the resonator mirrors is varied between 15 and 35 cm, with measured quality factors ranging from 10,000 to 100,000. Good agreement is obtained between the measured data and values calculated from scalar diffraction theory. The experimental effect of misaligning the mirrors is also examined experimentally.
