    摘要： A switching arrangement for applying voltage pulses across a load, comprising a plurality of capacitive elements (C1-C9) connected in series, and a first switch arrangement (S) connected to the series connection to apply voltage pulses to the load, and a second switch arrangement (S1, S2) connected to a capacitive element of the series connection, such that one of the capacitive elements (C1) can be switched out of or switched into the series connection, in order to produce voltage pulses of respectively lower or higher levels, without the need to dissipate energy into a resistive load.

    摘要： A linear accelerator is disclosed, having a series of interconnected cavities through at least some of which an rf signal and an electron beam are sent, comprising at least one variable coupler projecting into the a cavity of the series, a control apparatus adapted to interpret an electrical signal from the coupler and derive diagnostic information as to the electron beam therefrom, wherein the control apparatus is further adapted to vary the interaction of the at least one coupler with the rf signal in dependence on the diagnostic information. Thus, the accelerator properties can be adjusted by encouraging or inciting an Higher-Order Mode (“HOM”) having a desired effect such as bunching and/or deflecting. The coupler could be rotateable, and partially or fully retractable, to allow its influence to be adjusted and/or for it to be removed from service when not needed. Several such probes could be available, approaching the cavity from different directions or at different locations, or approaching different cavities. The coupler can be asymmetric, in order to exert an appropriate influence on the cavity and provoke a useful HOM. For example, it can be elongate with at least one directional deviation, such as a hockey stick. Generally, however, the appropriate shape for the coupler will be dependent on the shape of the cavity with which it is working and the specific HOMs that are to be excited.

    摘要： A separated-orbit bisected energy-recovered linear accelerator apparatus and method. The accelerator includes a first linac, a second linac, and a plurality of arcs of differing path lengths, including a plurality of up arcs, a plurality of downgoing arcs, and a full energy arc providing a path independent of the up arcs and downgoing arcs. The up arcs have a path length that is substantially a multiple of the RF wavelength and the full energy arc includes a path length that is substantially an odd half-integer multiple of the RF wavelength. Operation of the accelerator includes accelerating the beam utilizing the linacs and up arcs until the beam is at full energy, at full energy executing a full recirculation to the second linac using a path length that is substantially an odd half-integer of the RF wavelength, and then decelerating the beam using the linacs and downgoing arcs.

    摘要： The devices, systems and techniques disclosed here can be used to reduce undesired effects by magnetic field induced eddy currents based on a diamagnetic composite material structure including diamagnetic composite sheets that are separated from one another to provide a high impedance composite material structure. In some implementations, each diamagnetic composite sheet includes patterned conductor layers are separated by a dielectric material and each patterned conductor layer includes voids and conductor areas. The voids in the patterned conductor layers of each diamagnetic composite sheet are arranged to be displaced in position from one patterned conductor layer to an adjacent patterned conductor layer while conductor areas of the patterned conductor layers collectively form a contiguous conductor structure in each diamagnetic composite sheet to prevent penetration by a magnetic field.
