Abstract: An assembly of a support plate and an exit window foil for use in an electron beam device. The support plate is designed to reduce wrinkles in said foil, which wrinkles may arise due to surplus foil arising in the assembly process. The foil is being bonded to the support plate along a closed bonding line bounding a substantially circular area in which the support plate is provided with apertures and foil support portions and in which area the foil is adapted to serve as a portion of a wall of a vacuum tight housing of the electron beam device. Another aspect involves a method for using the assembly in a filling machine, as well as a method of reducing wrinkles.

Abstract: An apparatus and method for achieving an efficient central cathode in a Hall effect thruster is disclosed. A hollow insert disposed inside the end of a hollow conductive cathode comprises a rare-earth element and energized to emit electrons from an inner surface. The cathode employs an end opening having an area at least as large as the internal cross sectional area of the rare earth insert to enhance throughput from the cathode end. In addition, the cathode employs a high aspect ratio geometry based on the cathode length to width which mitigates heat transfer from the end. A gas flow through the cathode and insert may be impinged by the emitted electrons to yield a plasma. One or more optional auxiliary gas feeds may also be employed between the cathode and keeper wall and external to the keeper near the outlet.

Abstract: A solid-state vacuum device (SSVD) and method for making the same. In one embodiment, the SSVD forms a triode device comprising a substrate having a cavity formed therein. The SSVD further comprises a cathode positioned near the opening of the cavity, wherein the cathode spans over the cavity in the form of a bridge that creates an air gap between the cathode and substrate. In addition, the SSVD further comprises an anode and a grid that is positioned between the anode and cathode. Upon applying heat to the cathode, electrons are released from the cathode, passed through the grid, and received by the anode. In response to receiving the electrons, the anode produces a current. The current received by the anode is controlled by a voltage applied to the grid. Other embodiments of the present invention provide diode, tetrode, pentode, and other higher order device configurations.
