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.

An electronic system includes an external jacket; a wall of an internal cavity that is to be cooled; at least one fixed connection fixing the external wall of the internal cavity that is to be cooled to the external jacket; a heat-transport fluid cooling circuit comprising grooves on the external surface of the wall of the internal cavity and a sleeve comprising a flexible portion positioned flush with the external surface of the external wall of the internal cavity, thereby forming mini-canals with said grooves; a radial extension of the wall of the internal cavity creating connecting points intended to hold the sleeve in place; and a space between the external jacket and the sleeve at the flexible portion of the sleeve.

The present invention is a rectangular waveguide providing amplification of an electromagnetic wave via interaction with an electron beam in a linear interaction channel where the electron beam enters the waveguide at a first curved part of the waveguide, traverses the linear interaction channel and exits the waveguide at a second curved part of the waveguide.
