Abstract: A conventional (non-relativistic) magnetron provides megawatt-levels of power. The magnetron includes a fourteen vane slow wave structure that surrounds a fourteen turn helical cathode. An upstream coaxial waveguide is surrounded by a dish-shaped flange that accommodates a reflector chamber in communication with an upstream void and a downstream interaction chamber. The vanes of the slow wave structure are shaped to define fourteen resonant chambers therebetween with each of the resonant cavities having a wedge portion in communication with a neck portion.

Abstract: Embodiments herein are directed to a resonator for an ion implanter. In some embodiments, a resonator may include a housing, and a first coil and a second coil partially disposed within the housing. Each of the first and second coils may include a first end including an opening for receiving an ion beam, and a central section extending helically about a central axis, wherein the central axis is parallel to a beamline of the ion beam, and wherein an inner side of the central section has a flattened surface.

Abstract: Coherent electronic current is generated by generating and transmitting an electron bunch along a longitudinal axis. The electron bunch is then directed onto a target, wherein the target imparts a transverse spatial modulation to the electron bunch via diffraction contrast or phase contrast. The transverse spatial modulation of the electron bunch is then transferred to the longitudinal axis via an emittance exchange beamline, creating a periodically modulated distribution of coherent electronic current.

Abstract: Frequency adjustable quarter-wavelength resonators have a movable end wall defined by a surface of a sphere that is moved within the resonator tube. The sphere can be ferromagnetic, enabling it to be moved by magnetic interactions with moving external magnetic elements, or by a variable external magnetic field, controlled by power modulation to external electromagnets. The resonators can optionally be helical or otherwise curved, and the spherical shape of the structure forming the end wall enables it to navigate curves in the resonator tube.
