    摘要: For high-voltage devices such as particle accelerators, novel geometries for a triple-junction at which an insulator, an anode and a vacuum meet are disclosed. A singularity in the electric field at the triple-junction is eliminated, reducing dielectric flashover and allowing the devices to operate at higher voltages without breakdown. In one aspect, such a device includes a cathode, an anode having an anode surface exposed to a vacuum, and a dielectric body disposed between the cathode and anode, the dielectric body having a dielectric surface that is exposed to the vacuum, wherein the dielectric surface and the anode surface approach each other such that an angle measured across the vacuum between the dielectric surface and the anode surface decreases with decreasing distance between the dielectric surface and the anode surface until the dielectric surface and the anode surface meet and are parallel.

    摘要: The present invention relates to a dual-frequency resonant cavity (6) for cyclotron which includes a dee (10), a pillar (20), and a conducting enclosure (40) surrounding the pillar and the dee, an end of the pillar being connected to the base of the conducting enclosure and an opposite end of the pillar (20) supporting the dee (10). The conducting enclosure and the pillar form a transmission line comprising at least three portions (20a, 20b, 20c), each portion having a characteristic impedance (Zc1, Zc2, Zc3). The characteristic impedance Zc2 of the intermediate portion (20b) is substantially lower than the characteristic impedances Zc1 et Zc3 of the two other portions (20a, 20b), which makes it possible to have the cavity resonate according to two modes in order to produce two distinct frequencies, without having to make use of moving components such as for example sliding short-circuits or mobile plates.The present invention also relates to a method for designing such a resonant cavity, based on the use of electromagnetic—and radio frequency simulation tools.

    摘要: Fabrication methods for contoured polyhedral cavities for particle acceleration are disclosed. The process may include: trimming flat sheets to a conformal shape; bending the sheets to form a contour that is axially curved and azimuthally flat; and joining the sheets to form a circumferentially polyhedral cavity that is configured to support a resonant electromagnetic field at cryogenic temperatures. The resulting cavity may have ductile or even brittle superconducting materials with an axially-oriented grain structure at each point on the circumference of the cavity. As part of the assembly process, the sheets may be bonded to a supporting substrate of thermally conductive material having integrated cooling passages. The supporting substrates may be configured to have electrical contact near the cavity openings while having a small gap near the equators of the cavity. Moreover, mode-coupling channels and waveguides may be provided to extract energy from undesired deflection modes.

    摘要: A method of fabricating a spherical cavitation chamber is provided. Depending upon the chamber's composition and wall thickness, chambers fabricated with the disclosed techniques can be used with either low or high pressure systems. During chamber fabrication, initially two spherical half portions are fabricated and then the two half portions are joined together to form the desired cavitation chamber. During the fabrication of each chamber half, the interior spherical surface is completed first and then the outer spherical surface. Prior to joining the two spherical cavitation chamber halves, the surfaces to be mated are finished, preferably to a surface flatness of at least ±0.01 inches. Electron beam welding is used to join the chamber halves together. Preferably the electron beam welding operation is performed under vacuum conditions. During electron beam welding, the two chamber halves are aligned and held together while the electron beam forms a weld along the chamber seam.
