Abstract

A dielectric-wall linear accelerator is improved by a high-voltage, fast rise-time switch that includes a pair of electrodes between which are laminated alternating layers of isolated conductors and insulators. A high voltage is placed between the electrodes sufficient to stress the voltage breakdown of the insulator on command. A light trigger, such as a laser, is focused along at least one line along the edge surface of the laminated alternating layers of isolated conductors and insulators extending between the electrodes. The laser is energized to initiate a surface breakdown by a fluence of photons, thus causing the electrical switch to close very promptly. Such insulators and lasers are incorporated in a dielectric wall linear accelerator with Blumlein modules, and phasing is controlled by adjusting the length of fiber optic cables that carry the laser light to the insulator surface. 12 figs.

Linear particle accelerator with seal structure between electrodes and insulators

Patent Broadhurst, J.H.

This patent describes a linear accelerator. It includes a vacuum chamber, a pressure chamber exteriorly of the vacuum chamber, source means for producing a directed beam of charged particles inside the vacuum chamber, a target against which the beam of charged particles are directed, a plurality of similar circular electrodes disposed in substantially uniformly spaced apart, side-by-side relation. Each electrode being formed of an alloy comprised of iron, nickel, and cobalt, and each electrode having a substantially flat circumferential portion, and an axially offset portion located intermediate the central and circumferential portions. Each electrode having a centrally located opening inmore »« less
Linear particle accelerator with seal structure between electrodes and insulators

Patent Broadhurst, John H.

An electrostatic linear accelerator includes an electrode stack comprised of primary electrodes formed or Kovar and supported by annular glass insulators having the same thermal expansion rate as the electrodes. Each glass insulator is provided with a pair of fused-in Kovar ring inserts which are bonded to the electrodes. Each electrode is designed to define a concavo-convex particle trap so that secondary charged particles generated within the accelerated beam area cannot reach the inner surface of an insulator. Each insulator has a generated inner surface profile which is so configured that the electrical field at this surface contains no significantmore »« less

Plural cell battery. [rod-shaped electrodes which may pass straight through common wall between cells]

Patent Granqvist, C.E.

A plural-cell battery composed of a plurality of cells (primary or secondary) is described wherein the electrodes in adjacent cells are rod-shaped comprising a core of a plastic insulating material surrounded by active material in which several electrical leads of conductive material are imbedded. Electrodes of this type may be interconnected by conducting lines which are arranged to pass straight through the common wall between adjacent cells, or may be connected at one end to a pole bridge and thereby form a tubular plate electrode. 10 figures.

Superconducting, fast rise-time voltage source

Patent Lumley, R.M.

A pulse generator comprises a toroid of a superconducting material such as niobium on a glass or ceramic substrate. A cryogenic source such as liquid helium cools the toroid to within a few degrees of absolute zero and a perpetually circulatory current is set up in the toroid. A laser beam is fired at the toroid to cause localized heating and the resultant current drop due to the material resistance causes an output pulse to be induced in an adjacent current winding.
