Abstract
A quasi-optical version of the waveguide resonant ring is under development for testing high-power waveguide windows and components used in electron cyclotron heating (ECH) of plasmas and similar applications. A low-loss resonant ring can produce traveling waves at power levels typically 10 times greater than the input power. A quasi-optical version of the resonant ring is proposed by using oversized waveguide (smooth wall or corrugated), miter bends, and bellows for adjusting the ring length into resonance. This scheme will be useful for testing windows and other low-loss components at several times the available source power level. Off-line testing of windows using presently operating, lower-power gyrotrons will greatly simplify the development of higher power gyrotrons and barrier windows.
