摘要： Embodiments of systems, devices, and methods relate to initiating beam transport for an accelerator system. An example method includes increasing a bias voltage of one or more electrodes of the accelerator system to a first voltage level and extracting a charged particle beam from a beam source such that the beam is transported through the accelerator system. The beam has a beam current that results in a first transient voltage drop within a threshold. The method further includes increasing the beam current at a rate that results in one or more subsequent transient voltage drops within the threshold until the accelerator system has reached nominal conditions. Another example method includes biasing one or more electrodes of an accelerator system and selectively extracting, according to a duty cycle function, a charged particle beam from a beam source such that the charged particle beam is transported through the accelerator system.

摘要： 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.

摘要： Example embodiments of systems, devices, and methods are provided herein for energy systems having multiple modules arranged in cascaded fashion for storing power from one or more photovoltaic sources. Each module includes an energy source and converter circuitry that selectively couples the energy source to other modules in the system over an AC interface for generating AC power or for receiving and storing power from a charge source. Each module also includes a DC interface for receiving power from one or more photovoltaic sources. Each module can be controlled by control system to route power from the photovoltaic source to that modules energy source or to the AC interface. The energy systems can be arranged in single phase or multiphase topologies with multiple serial or interconnected arrays. The energy systems can be arranged such that each module receives power from the same single photovoltaic source, or multiple photovoltaic sources.

摘要： Example embodiments of systems, devices, and methods are provided for electric vehicles that are subject to intermittent charging, such as rail-based electric vehicles, having one or more modular cascaded energy systems. The one or more modular systems can be configured to supply multiphase, single phase, and/or DC power to numerous motor and auxiliary loads of the EV. If multiple systems or subsystems are present in the EV, they can be interconnected to exchange energy between them in numerous different ways, such as through lines designated for carrying power from the intermittently connected charge source or through the presence of modules interconnected between arrays of the subsystems. The subsystems can be configured as subsystems that supply power for motor loads alone, motor loads in combination with auxiliary loads, and auxiliary loads alone.
