    Abstract: Provided is an ion beam treatment apparatus. The treatment apparatus includes a target for generating positive ions including a thin film for generating positive ions and nanowires disposed on at least one side of the thin film for generating positive ions, and a laser for emitting a laser beam incident on nanowires to project positive ions to a tumor region of a patient by generating the positive ions from the thin film for generating positive ions. Each of the nanowires may include a metal nanocore and a polymer shell surrounding the metal nanocore. The laser beam incident on the nanowires forms surface plasmon resonance, a near field having an intensity enhanced more than an intensity of the laser beam is formed by the surface plasmon resonance, and the positive ions are emitted from the thin film for generating positive ions by the near field.

    Abstract: A deceleration apparatus capable of decelerating a short spot beam or a tall. ribbon beam is disclosed. In either case, effects tending to degrade the shape of the beam profile are controlled. Caps to shield the ion beam from external potentials are provided. Electrodes whose position and potentials are adjustable are provided, on opposite sides of the beam, to ensure that the shape of the decelerating and deflecting electric fields does not significantly deviate from the optimum shape, even in the presence of the significant space-charge of high current low-energy beams of heavy ions.

    Abstract: The invention describes a particle source in which energy selection occurs. The energy selection occurs by sending a beam of electrically charged particles 103 eccentrically through a lens 107. As a result of this, energy dispersion will occur in an image formed by the lens. By projecting this image onto a slit 109 in an energy selecting diaphragm 108, it is possible to allow only particles in a limited portion of the energy spectrum to pass. Consequently, the passed beam 113 will have a reduced energy spread. Deflection unit 112 deflects the beam to the optical axis 101. One can also elect to deflect a beam 105 going through the middle of the lens toward the optical axis and having, for example, greater current.The energy dispersed spot is imaged on the slit by a deflector 111. When positioning the energy dispersed spot on the slit, central beam 105 is deflected from the axis to such an extent that it is stopped by the energy selecting diaphragm. Hereby reflections and contamination resulting from this beam in the region after the diaphragm are avoided. Also electron-electron interaction resulting from the electrons from the central beam interacting with the energy filtered beam in the area of deflector 112 is avoided.

    Abstract: The invention comprises a negative ion source method and apparatus used as part of an ion beam injection system, which is used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. The negative ion source preferably includes an inlet port for injection of hydrogen gas into a high temperature plasma chamber. In one embodiment, the plasma chamber includes a magnetic material, which provides a magnetic field barrier between the high temperature plasma chamber and a low temperature plasma region on the opposite side of the magnetic field barrier. An extraction pulse is applied to a negative ion extraction electrode to pull the negative ion beam into a negative ion beam path, which proceeds through a first partial vacuum system, through an ion beam focusing system, into the tandem accelerator, and into a synchrotron.
