Abstract
A high energy discharge apparatus uses a generally electron transparent thin foil anode of various configuration which is arranged parallel to and spaced apart between a pair of cathodes, and energized to create a potential difference between the anodes and cathodes causing electrons to be reflected back and forth through the foil anode with the concurrent discharge of ions being accelerated to the cathode.
Claims13
A reflex diode comprising
- means defining an evacuated chamber,
- a pair of cathodes arranged spaced apart from each other in said chamber
- a generally electron transparent thin foil anode disposed between, and spaced apart from said cathodes, in said chamber, whereby electrons are multiply reflected between said cathodes and
- means for creating an electrical potential difference between said cathodes and said anode.

A reflex diode comprising
- means defining an evacuated chamber,
- a cathode disposed in said chamber,
- a first electron opaque anode disposed spaced apart from said cathode in said chamber,
- a second generally electron transparent thin foil anode disposed spaced apart between said cathode and said first anode and electrically connected to said first anode in said chamber, whereby a virtual cathode is created between said first and second anodes, and
