    Abstract: A method and apparatus is disclosed for electrostatic deflection and focusing of a charged particle stream. The apparatus can include plural vertical and horizontal deflection plates, although a single vertical and a single horizontal deflection plate each with a reference potential plane are preferred. Both orthogonal and preferably tilted display screens are employed to receive the deflected beam. The particle stream is injected offset from a centered position and the stream is deflected asymmetrically relative to the attracting deflection plate. Two alternately preferred computer programs are employable to calculate an offset position. A preferred external quadrupole is employed to correct any residual astigmatism in the particle stream. In one embodiment, the apparatus is disposed in a cathode ray tube. A reduced footprint CRT is also disclosed. Methods and apparatuses for an energy filtered electron beam, a mass spectrometer and a mass separator are also disclosed.

    Abstract: A multi-mass filter for separating particles of a multi-species plasma includes a chamber, which defines an axis. A radial electric field is crossed with a magnetic field (E×B) to move the particles of different mass (M1, M2 and M3) on respective trajectories into respective first, second and third regions. Specifically, particles M1 are confined in the first region, while both particles M3 and M2 are ejected from the first region into the second region and only the particles M3 are ejected from the second region into the third region.

    Abstract: An apparatus is provided for use in determining the components of an inputted gas mixture. The apparatus includes a single piece body or framework preferably made of a high insulating material, such as ceramic. The body includes a number of cut-outs for receiving or incorporating hardware used in generating ions, controlling their movement, and directing them to an ion collector plate. One of the cut-outs formed in the insulating body receives an ion source assembly. Another of the cutouts is a passageway with metallized material coated along the walls thereof for use in generating an electric field. A third cut-out receives and is associated with a magnet assembly used in directing ion movement towards the collector plate. The single body and cut-out construction reduces the number of individual parts, improves the assembly of such parts and reduces adjustment time associated with such parts. The magnetic assembly is formed using pairs of identical parts in a sandwich-like construction to also facilitate assembly of the apparatus. The body also includes a number of feed through holes for receiving conducting pins. The locations of the holes are precisely formed in the body and the conducting pins are used in providing electrical communication between apparatus parts and control hardware.
