ABSTRACT:
An improved thermionic electric converter uses a wire grid cathode to provide a larger surface area for electrons to boil off. Alternately or additionally, the larger electron emission surface area can be achieved by using a curved electron emission surface. A laser provides quantum interference to electrons just before they reach the anode, thereby lowering their energy levels such that they more readily are captured by the anode. The arrangement provides improved conversion efficiency and reduced electron scatter.
