    摘要: An interdigital (Wideröe) linear accelerator employing drift tubes, and associated support stems that couple to both the longitudinal and support stem electromagnetic fields of the linac, creating rf quadrupole fields along the axis of the linac to provide transverse focusing for the particle beam. Each drift tube comprises two separate electrodes operating at different electrical potentials as determined by cavity rf fields. Each electrode supports two fingers, pointing towards the opposite end of the drift tube, forming a four-finger geometry that produces an rf quadrupole field distribution along its axis. The fundamental periodicity of the structure is equal to one half of the particle wavelength βλ, where β is the particle velocity in units of the velocity of light and λ is the free space wavelength of the rf. Particles are accelerated in the gaps between drift tubes. The particle beam is focused in regions inside the drift tubes.

    摘要: A video display apparatus includes a cathode ray tube and a high voltage transformer. The high voltage transformer incorporates a high voltage winding for producing an anode voltage in the cathode ray tube. The high voltage winding has a tap which provides a focus voltage for the electron gun assembly of the cathode ray tube. The transformer also includes a primary winding which is included in a resonant circuit. A third winding has a second portion that is wound to be closely coupled to the portion of the high voltage winding not associated with the generation of focus voltage. The third winding is coupled between the primary winding and a capacitor to produce a current that controls a variation of a ratio between the focus voltage and the anode voltage as a function of variation in a beam current in the cathode ray tube.

    摘要: A magnetic array for periodic magnetic devices is formed as a series of pole modules each constructed from rectangular components. Field strengths in excess of 2.0 T are achieved by surrounding each pole module on all available sides with magnet blocks. Less magnet material is used than in prior modules that produced equal field strengths and magnet material is more efficiently used by reducing the material scrap associated with manufacture of prior art pole and magnet designs.

    摘要: Some electrons reflected from the collector of a klystron form a beam current flowing back toward the input end of the tube. This beam is modulated and can carry a regenerate signal which distorts the tube's performance when amplifying a television signal. The reflected electrons are removed by a spiralling transverse magnetic field having a pitch equal to the cyclotron wavelength in the axial magnetic field used to focus the beam. The rotative sense of the spiral is such that forward-going beam electrons are not affected but returning electrons are accelerated in their cyclotron orbits until they are driven outside the beam and are collected.

    摘要: A novel apparatus and method for focussing beams of charged particles comprising planar arrays of electrostatic quadrupoles. The quadrupole arrays may comprise electrodes which are shared by two or more quadrupoles. Such quadrupole arrays are particularly adapted to providing strong focussing forces for high current, high brightness, beams of charged particles, said beams further comprising a plurality of parallel beams, or beamlets, each such beamlet being focussed by one quadrupole of the array. Such arrays may be incorporated in various devices wherein beams of charged particles are accelerated or transported, such as linear accelerators, klystron tubes, beam transport lines, etc.

    摘要: In a microwave tube of the type wherein an electron beam emitted by an electron gun is focused and caused to interact with an input high frequency wave at a high frequency circuit unit by magnetic flux generated by a permanent magnet type magnetic circuit, and the electron beam after the interaction is collected by a hollow cylindrical collector, a leakage flux generating means is provided near the entrance of the collector for generating leakage flux acting upon the electron beam. The leakage flux is produced by providing a notch for a pole piece adjacent to the collector and connected to the high frequency circuit unit or by reducing the cross-sectional area of the pole piece for magnetically saturating the pole piece itself or by keeping the pole piece in contact only with a portion of one end of the permanent magnet.

    摘要: An improved traveling wave tube and method of manufacturing same is disclosed. The tube has an elongated housing with a central evacuated passageway. There are a plurality of beam focusing annular magnets supported within the housing around the passageway at predetermined spaced locations along the length of the passageway and a slow wave circuit supported within the housing in predetermined relationship with respect to the magnets. The housing is a pair of joined semi-cylindrical mating ceramic substrate halves, each half including semi-annular grooves along its part of the passageway which register with respective semi-annular grooves of the other half to define annular grooves which receive and support the magnets. The ceramic substrate halves have conductive material deposited therein that forms the slow wave circuit. The associated method comprises the steps of forming first and second semi-cylindrical substrate halves with rib-like constrictions and recesses for the slow wave circuit and grooves for the magnets, depositing the slow wave circuit in both halves providing magnets in the grooves; and joining the halves together with the grooves and slow wave portions on both halves in registration.
