A method and apparatus is disclosed for an electron beam directed energy
device. The device consists of an electron gun with one or more electron
beams. The device includes one or more accelerating plates with holes
aligned for beam passage. The plates may be flat or preferably shaped to
direct each electron beam to exit the electron gun at a predetermined
orientation. In one preferred application, the device is located in outer
space with individual beams that are directed to focus at a distant
target to be used to impact and destroy missiles. The aimings of the
separate beams are designed to overcome Coulomb repulsion. A method is
also presented for directing the beams to a target considering the
variable terrestrial magnetic field. In another preferred application,
the electron beam is directed into the ground to produce a subsurface
x-ray source to locate and/or destroy buried or otherwise hidden objects
including explosive devices.
