    摘要: Devices and methods are provided to allow rapid deflection of a charged particle beam. The disclosed devices can, for example, be used as part of a hadron therapy system to allow scanning of a target area within a patient's body. The disclosed charged particle beam deflectors include a dielectric wall accelerator (DWA) with a hollow center and a dielectric wall that is substantially parallel to a z-axis that runs through the hollow center. The dielectric wall includes one or more deformed high gradient insulators (HGIs) that are configured to produce an electric field with an component in a direction perpendicular to the z-axis. A control component is also provided to establish the electric field component in the direction perpendicular to the z-axis and to control deflection of a charged particle beam in the direction perpendicular to the z-axis as the charged particle beam travels through the hollow center of the DWA.

    摘要: A high-frequency acceleration type ion acceleration and transportation apparatus is a beamline after an ion beam is accelerated by a high-frequency acceleration system having an energy spread with respect to set beam energy and includes an energy analysis deflection electromagnet and a horizontal beam focusing element. In the ion acceleration and transportation apparatus, a double slit that is configured by an energy spread confining slit and an energy analysis slit is additionally disposed at a position at which energy dispersion and a beam size are to be appropriate. The position is determined based on a condition of the energy analysis deflection electromagnet and the horizontal beam focusing element, and the double slit performs energy separation and energy definition and decreases the energy spread of the ion beam by performing adjustment for a smaller energy spread while suppressing a decrease in the amount of a beam current.

    摘要: A high-accuracy and high-speed lithographic pattern is acquired by forming a square lattice matrix beam group with an interval which is an integral multiple of a beam size in a two-dimensional plane, switching on and off the mesh of a device to be drawn by a bitmap signal, forming a desired beam shape, deflecting the beam to a necessary position, and radiating a beam with a whole blanker being opened after the beam state is stabilized. On and off signals and a vector scan signal of each beam are provided, and the whole blanker is released after the beam is stabilized, and thus high-accuracy and high-speed lithography is performed with a small amount of data. When the total number of shots exceeds a constant value, the pattern data are modified and high-speed lithography is achieved. A semiconductor reversed bias p-n junction technique is preferably used for an individual blanker electrode.
