Abstract: A method and apparatus for producing ions wherein an ion generator produces periodic pulses of electric energy of a single polarity for some applications and alternating positive and negative polarities for other applications. A plurality of the electric pulses are limited in amplitude by a substantially sinusoidal half-wave envelope and the positive and negative pulses are preferably of different amplitudes. The ground electrode is arranged about and upstream and downstream of the ionizing electrode to provide a highly effective electric field substantially normal to the gas flow. A heater heats the gas to increase ionization. An ultrasonic sound wave generator pulses the gas with sound waves prior to, during or after ionization of the gas to group the ions of a like charge in distinct pressure wave fronts or distinct areas so as to reduce recombination of ions thereby making more ions available per volume and also increasing the total energy of the ions produced. Multiple sound wave generators increase the energy of the base frequency or selected harmonics. An inlet passage to the generator of a selected length increases the energy. A discharge passage of a selected length reinforces and/or eliminates selected harmonics. A discharge nozzle with angularly inclined and outwardly enlarged venturis cool the heated ionized gas.

Abstract: An ion generating apparatus and a method of treatment is disclosed which includes means for generating positively charged ions and means for generating negatively charged ions. A timer is provided which alternately energizes the negative ion generator and the positive ion generator in a predetermined time sequence so that the apparatus alternately emits negative ions and positive ions. The patent is thus alternately subjected to a flow of negative and positive ions.

Abstract: An electron discharge tube, for example a travelling wave tube, which employs a periodic magnetic field, is provided with at least one pair of adjacent magnets with larger spacing in the axial direction than is employed between the magnets of other adjacent pairs. The perturbation of the field due to the larger spacing is reduced by providing only one pole piece interposed between the two magnets on each side of the larger spacing. The remaining pairs of magnets may have normally spaced pole pieces. The larger spacing may be occupied by a waveguide connection.

Abstract: A deceleration apparatus capable of decelerating a short spot beam or a tall ribbon beam is disclosed. In either case, effects tending to degrade the shape of the beam profile are controlled. Caps to shield the ion beam from external potentials are provided. Electrodes whose position and potentials are adjustable are provided, on opposite sides of the beam, to ensure that the shape of the decelerating and deflecting electric fields does not significantly deviate from the optimum shape, even in the presence of the significant space-charge of high current low-energy beams of heavy ions.
