Abstract: A linear accelerator head for use in a medical radiation therapy system can include a housing, an electron generator configured to emit electrons along a beam path, and a microwave generation assembly. The linear accelerator head may include a waveguide that is configured to contain a standing or travelling microwave. The waveguide can include a plurality of cells that are disposed adjacent one another, wherein each of the plurality of cells may define an aperture configured to receive electrons therethrough. The linear accelerator head can further include a converter and a primary collimator.

Abstract: A pluggable optical/electrical module is disclosed. One or more features operate to decrease electromagnetic interference are implemented, which features include deforming the portions that mate together to form the housing, placing elbow deformities on extending fingers to more properly seal the housing convex shape to housing to seal gaps between multiple sections, and placing an EMI insulating material within an opening that is formed for the latch that locks the module in place in a chassis.

Abstract: A low form-factor transceiver system appropriate for long-reach optical communications is presented. In accordance with the present invention, an electronic interface to a receiver optical sub assembly (ROSA) and a transmitter optical sub assembly (TOSA) is arranged on a multi-layer board to electrically shield the transmitter and receiver portions from a high-voltage power supply, which is utilized to provide bias voltages to optical detectors in the ROSA. In some embodiments of the invention, the high-voltage power supply is arranged on a top layer while the transmitter and receiver are arranged on a bottom layer in a split-ground arrangement. Layers between the top layer and the bottom layer include at least one ground plane and provide vias for electrical connections.

Abstract: An apparatus and method for making single crystals of a high melting point substance by a crucibleless skull process are provided wherein the apparatus operates with less power consumption than comparable prior art systems. The apparatus utilizes a self-sealing and self-venting charge comprising a mass of the substance with a preformed vent therein, the mass being held and retained by a side wall made of a felt of the substance. The charge is retained by an encircling plurality of rods comprising a nonsusceptible material. The charge is heated by RF induction from the center of the charge to form a melt which extends outward. The melt is extended longitudinally by translating the charge in the RF field.
