A circle is placed at the launch point to improve the interaction between the electron beam and the fields supported by the slow wave structure, thus to control the beam current density at the launch point, and to minimize the loss of the electron beam energy. The inaner radii of the extractor vanes are slightly larger than those of other SWS vanes, which increases the axial group velocity and enhances the microwave output power and efficiency. Implementation of two RF choke vanes stops the leakage of microwave pulse power toward the diode, and makes the device more compact than the conventional MILO.
