“…Later, however, it was shown [10] that in higher power (about 30 W) nanosecond 3 cm range GDOs, the microwave oscillation phase is also stable at a fixed point on the leading edge of the voltage pulse if its rise time τ e ≈ 4.5 ns, which is much longer than the oscil lation period. Because of this, the phase stabilization in 3 cm range 30 W nanosecond GDOs is studied in greater detail experimentally and by numerical simu lation.…”
