摘要： Apparatus for focusing beams of charged particles comprising planar arrays of electrostatic quadrupoles. The array may be assembled from a single component which comprises a support plate containing uniform rows of poles. Each pole is separated by a hole through the plate designed to pass a beam. Two such plates may be positioned with their poles intermeshed to form a plurality of quadrupoles.

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： A technique for compensating for chromatic aberration in particle beams, caused by differing particle energy levels when a beam is deflected for beam steering or beam focusing. A compensating deflection is applied to the beam upstream of its intended point of deflection. When the particles reach the point of deflection, the effect of the compensating deflection is proportional to the energy level of each particle, and compensates for the aberration that would normally occur. The point at which the compensating deflection is applied is selected to be one-fourth of a cycle in longitudinal phase space and an integral number of half-cycles in transverse phase space. With this critical spacing, the compensating deflection at the point of its application is proportional to relative phase in longitudinal phase space, but is proportional to energy level at the intended point of deflection.

摘要： A technique for correcting spherical and other aberrations in a particle beam. Spherical aberration is caused by variations in beam behavior dependent on the cube of the radius or radial position with respect to the beam axis. To correct for such aberration, the beam is passed through multiple compensation electric field arrays, each of which has multiple rows of parallel wires stretched transversely across the beam path, the rows being biased with separate voltages to provide an electric field that varies in proportion to the cube of the distance from the central row of the array. The multiple arrays provide a cylindrically symmetrical electric field, and are oriented at a uniform angular spacing, which, for spherical aberration, is 120 degrees.

摘要： A klystron includes a source for emitting at least one electron beam, and an accelerator for accelarating the beam in a given direction through a number of drift tube sections successively aligned relative to one another in the direction of the beam. A number of electrostatic quadrupole arrays are successively aligned relative to one another along at least one of the drift tube sections in the beam direction for focusing the electron beam. Each of the electrostatic quadrupole arrays forms a different quadrupole for each electron beam. Two or more electron beams can be maintained in parallel relationship by the quadrupole arrays, thereby enabling space charge limitations encountered with conventional single beam klystrons to be overcome.
