摘要： A continuous wave (CW) electron accelerator for the treatment of industrial streams including an electron beam source, a modified high efficiency slot coupled cavity, at least one focusing magnet positioned surrounding the accelerator to contain the beam in the accelerator, an efficient radio frequency power supply means for supplying power of a radio frequency to the cavity to induce a TM01 accelerating mode in the cavity, an electron beam spreader or raster, a fixed magnet array or two-dimensional scanning magnet for deflecting the accelerated beam into a desired shape, and an exit window for extracting the deflected electron beam. The accelerator includes a graded-beta cavity to enable use with a low-power pulsed electron source. The accelerator benefits from a low wall-power loss accelerating cavity that is energized with efficient RF sources, enabling it to be operated in continuous wave mode.

摘要： Spin polarized beams are an essential tool in the study of nuclear physics using particle accelerators. Particle accelerators can produce spin polarized beams, but a technology is needed to continuously monitor, in real time and non-invasively, the beam's polarization direction and quality. Without this capability, there is no way to automate polarization quality optimization. The ring-coupled cavity resonator provides a mechanism to enhance the interaction between a cavity resonator and the spin of passing particles, and provides a method to determine and monitor, in real time and non-invasively, beam magnetization and longitudinal spin polarization direction and quality.

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： The present invention is an RF cavity for accelerating electrons in imaging applications such as x-ray tubes and CT applications. An RF cavity having electron emitters placed therein accelerates the electrons across the cavity. The geometric shape of the cavity determines the electromagnetic modes that are employed for the acceleration of electrons. The fast electrons are used to generate x-rays by interacting with a target, either a solid or a liquid target. The electron accelerator may be used in an arc source for a stationary computed tomography application, in an x-ray tube, as a booster for an electron gun, and other imaging applications.

摘要： A dished head and a wall part are integrally formed in one body by spinning, using a flat aluminum based material, and then a corrosion-proof protective coating is formed on the whole surface by the Irridite process to complete the canister. The combination of appropriate material selection and production process saves the processing time (man-hour) needed for forming resonator canisters and its surface treatment, improves the thermal conductivity, and consequently decreases individual differences of the radio frequency loss in resonator canisters.
