The present disclosure provides a self-contained system that contains a plurality of target cartridges, automatically inserts a selected target cartridge into position for irradiation, advances a foil to facilitate irradiation over the target chamber, replaces the foil for additional irradiation (if desired), serves as a dissolution cell for retrieval of the irradiated material, removes the used target cartridge and inserts a new cartridge for subsequent cycles of operation. Consequently, only the dissolved target material and dissolution medium are transferred between the target system and any post processing cells/labs. Accordingly, a system is disclosed for processing a target material without disturbance to irradiated material (thereby eliminating risk of impurities) and without requiring manual access/intervention (thereby eliminating risk of exposure).

Embodiments of systems, devices, and methods relate to selecting a raster profile for scanning a proton beam across a target. A raster profile is selected from among the plurality of plurality of possible raster profiles based on a value of a figure of merit. A beam is directed across the target surface to form a pattern that is repeated one or more times at different radial orientations to form a scanning profile. A target temperature is monitored while scanning the beam across the target surface according to the scanning profile. The scanning parameters are changeable to avoid target damaging, to improve thermal performance and to optimize particle loading.

A synchrocyclotron for extracting charged particles accelerated to an extraction energy includes a magnetic unit comprising N valley sectors and N hill sectors, and configured for creating z-component of a main magnetic characterized by a radial tune of the successive orbits. The synchrocyclotron includes a first instability coil unit and a second instability coil unit configured for creating a field bump of amplitude increasing radially. The amplitude of the field bump may be varied to reach the value of the offset amplitude at the average instability onset radius. The offset amplitude may be the minimal amplitude of the field bump at the average instability onset radius required for sufficiently offsetting the center of the orbit of average instability onset radius to generate a resonance instability to extract the beam of charged particle at the average instability onset radius.

A gantry-less particle therapy system is provided. Charged particles are extracted from an ion source and accelerated in a beam transport system having an annular portion extending in a first plane and that circumscribes a volume, an arcuate portion extending in a second plane, and a transition portion that connects the annular portion and the arcuate portion. The arcuate portion terminates at a beam nozzle extending radially inward from the annular portion to deliver an ion beam to a treatment area contained in the volume circumscribed by the annular portion.
