Abstract
An apparatus for modulating the density of an electron beam as it is emitted from a cathode, comprised of connecting a source of pulsed input power to the input end of a nonlinear transmission line and connecting the output end directly to the cathode of an electron beam diode by a direct electrical connection.
Claims10
An apparatus for modifying the density of an electron beam being emitted from a cathode comprising:
- a nonlinear transmission line having an output;
- an electrical connection for connecting the nonlinear transmission line to a source of pulsed output power;
- an electron beam diode having a cathode;
- and
- an electrical connection for connecting the output of the nonlinear transmission line to the cathode of the electron beam diode.
An apparatus for modifying the density of an electron beam as the beam is being emitted from a cathode, comprising:
- a nonlinear transmission line having an impedance and an output;
- an electrical connection for connecting the nonlinear transmission line to a source of pulsed input power;
- the output of the nonlinear transmission line for being connected to an impedance transformer having a transformer output;
- an electron beam diode having a cathode and having an electron beam diode impedance;
- and
- the transformer output for being connected to the cathode of the electron beam diode, for matching the electron beam diode impedance with the impedance of the nonlinear transmission line.
