Abstract: A high performance field reversed configuration (FRC) system includes a central confinement chamber, divertors coupled to the ends of the chamber, neutral beam injectors positioned about the chamber, and a magnetic system comprising quasi-dc coils axially positioned along the FRC system components.

Abstract: Embodiments that are directed to a target for producing a high epithermal neutron yield for boron-neutron capture therapy (BNCT) treatments are disclosed. The target includes a thin flat film of solid lithium mounted onto a heat-removal support structure that is cooled with a liquid coolant and configured to maintain the turbulent flow regime for a liquid coolant and distribute the flow of coolant directed at the center of the support structure toward a periphery of the support structure via a plurality of channels formed in the support structure. The support structure includes a nozzle located at its center to direct coolant flow outwardly from the center to avoid stagnant water flow at the center of the support structure. Systems, device, and methods utilizing the approaches are also described.

Abstract: Embodiments are provided relating to the exchange of devices or assemblies holding targets used in a beam system. With these embodiments a used target can be rapidly and safely replaced with a new target to permit continued operation in a clinical or other environment. Also provided are embodiments of valves having relatively lower profiles that facilitate engagement and disengagement of beamline sections for access to the target device or assembly. All or a portion of the valve can be part of the target assembly. Also provided are embodiments of storage containers for storing a volatile object, such as an object comprising a composition sensitive to atmospheric air and/or an object that is radioactive. The storage container can include a two-part shell case assembly configured for housing a volatile object between the two parts, which engage one another to form an air-tight seal therebetween.

Abstract: Embodiments of systems, devices, and methods relating to a charge exchange system having one or more guard apparatuses are described. The guard apparatuses can include one or more guard electrodes, optionally with one or more screen electrodes. Also described are embodiments of beam systems incorporating one or more charge exchange systems.

Abstract: A system for vaporizing a powder material incorporates a laser source with an optical arrangement for generating and focusing a laser beam to a focal point. The beam is characterized by having a region with a converging/diverging angle (?), respectively upstream/downstream from the focal point. It also has a power density above a predetermined value within the region. A conduit is provided with a channel, and the laser beam is focused to conform to the region in the channel. A nozzle then directs powdered material into the laser beam at a location upstream from the region for vaporization of the powder material by the laser beam during its transit through the region.
