概要

Fast oscillation startup in a strapped magnetron using electrically primed electrons is demonstrated by a three-dimensional particle-in-cell simulation. The electrons are electrically primed by five-fold perturbation of the radial electric field along the azimuthal direction in a 10-vane strapped magnetron, and this leads to fast oscillation startup in the desired $\pi$-mode. The start of oscillation is advanced from 62 to 52 ns, and the time at which the steady state is reached from 130 to 85 ns when the radial variation of the protrusion and recession of the central region of the anode is 0.3 mm with an angular width of 0.5 mm.
