    Abstract: A cathode operating temperature adjusting method includes acquiring an approximate equation approximating a correlation between an emission current value in an electron beam source using a cathode and an operating temperature of the cathode at which a bias voltage becomes saturated at the emission current, measuring a current density of an electron beam from the cathode when in the state where an n-th emission current value and an n-th cathode operating temperature are set in the electron beam source, determining whether the measured current density is within a first tolerance range, changing the n-th emission current value to an (n+1)th emission current value when the measured current density is not within the first tolerance range, calculating an operating temperature of the cathode corresponding to the (n+1)th emission current value by the approximate equation, and setting the calculated operating temperature, as an (n+1)th cathode operating temperature, in the electron beam source.

    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 present disclosure provides for various advantageous methods and apparatus of controlling electron emission. One of the broader forms of the present disclosure involves an electron emission element, comprising an electron emitter including an electron emission region disposed between a gate electrode and a cathode electrode. An anode is disposed above the electron emission region, and a voltage set is disposed above the anode. A first voltage applied between the gate electrode and the cathode electrode controls a quantity of electrons generated from the electron emission region. A second voltage applied to the anode extracts generated electrons. A third voltage applied to the voltage set controls a direction of electrons extracted through the anode.

    Abstract: A particle beam transport system used for particle radiation therapy is provided. A beam of particles exiting from an accelerator is transported at fixed energy for treatment of patients in one or more treatment rooms using permanent magnets. In one embodiment, the system includes a series of fixed-magnetic-field permanent magnets as beam focusing elements that transport the beam at fixed energy to a point where the constant energy beam can be modified for use independently in different treatment rooms. In some embodiments, the particle beam may be deflected using dipole or Lambertson magnets manufactured using permanent magnetic material. The system may also incorporate a matching section imposed as the beam exits the accelerator. The matching system includes diagnostic elements and feedback systems that verify the beam properties as it exits the accelerator, and modify it, if necessary, until the beam attains a desired energy value.
