    摘要: A field emission device is configured with a grid that includes nanotubes or nanowires. In one embodiment a cathode, an anode, and a nanotube or nanowire grid are responsive to inputs to produce a potential barrier between the grid and at least one of the cathode and the anode such that a set of electrons from the cathode can tunnel through the potential barrier to produce a net current at the anode.

    摘要: System that focuses electron beams in an electro-static area to a laminar flow of electrons with uniform distribution of current density and extraordinary demagnification includes a housing having a first interior portion and a second interior portion electrically insulated from the first interior portion. The second interior portion has an electric field-free space. An electrode system is disposed in the first interior portion and includes a cathode assembly and at least one anode assembly. The cathode assembly generates an electron beam that passes through each anode assembly and then into the electric field-free space in the second interior portion. The system parameters may be calculated and created due to the CGMR conceptual method.

    摘要: A high strength window for a radiation detection system includes a plurality of intersecting ribs defining a grid having openings therein with tops of the ribs terminate substantially in a common plane. The intersecting ribs are oriented non-perpendicularly with respect to each other and define non-rectangular openings. The window also includes a support frame around a perimeter of the plurality of intersecting ribs, and a film disposed over and spanning the plurality of intersecting ribs and openings. The film is configured to pass radiation therethrough. An associated radiation detection system includes a sensor disposed behind the window. The sensor is configured to detect radiation passing through the high strength window.
