Abstract
A superconducting cavity has a long time constant when the coupling factor of its output port is low so as to accumulate input microwave energy therein, and after a certain accumulation of the input microwave, an output microwave pulse with a large power is extracted from the cavity by suddenly increasing the coupling factor of its output port.
