Abstract:
A tool for patterning a disk such as a magnetic media disk for use in a disk drive system. The tool includes a chamber and a first and second series of magnets, each evenly spaced about the chamber wall. An ion beam source at an end of the chamber emits an ion beam toward the disk which is held within the chamber. The first series of magnets deflect the ion beam away from center and toward the chamber wall. The second ion beam source deflects the ion beam back toward the center so that the ion beam can strike the disk at an angle. In addition, to bending the ion beam, the magnets also rotate the bent ion beam so the movement of the ion beam revolves within the chamber.
Abstract:
The invention comprises a patient positioning and/or repositioning system, such as a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle radiation therapy. Patient positioning constraints optionally include one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are preferably movable and/or under computer control for rapid positioning, repositioning, and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the charged particle beam path to accurately and precisely target the tumor, and/or in system verification and validation.

Abstract:
A method and a device for changing direction of movement of a beam of accelerated charged particles are based on the use of a curved channel which is made from a material that is able to be electrically charged, and formation of the same kind of charge on an inside surface of the channel wall as that of the particles. Maintenance of a condition that relates an energy and a charge of the particles to geometrical parameters of the channel is required, in particular, a radius R of curvature of a longitudinal axis thereof, and to electrical strength of the wall material. The beam can possibly be rotated through large angles without loss of intensity, significantly simplifying a design, and also reducing the mass and dimensions of all devices, particularly by obviating a need for magnets and supply voltage and control voltage sources for such devices.
Abstract:
The inventions relate to a group that includes means for directing charged particles, enabling the acceleration and interaction thereof, and producing radiation caused by their movement, namely a method for changing the direction of an accelerated charged particle beam, a device for implementing said method, a source of undulator electromagnetic radiation, a linear and a circular charged particle accelerator, and a collider and means for producing a magnetic field created by a stream of accelerated charged particles. The method and the device for implementing same are based on the use of a curved channel (1) for transporting particles, which is made from a material that is able to be electrically charged, and the formation of the same kind of charge on the inside surface of the channel wall as that of the particles. The characterizing feature of these inventions is that they require the maintenance of a condition that relates the energy and the charge of the particles to the geometrical parameters of the channel, in particular the radius R of curvature of the longitudinal axis (14) thereof, and to the electrical strength of the wall material. The other devices in this group include a device for changing the direction of a beam, which defines the trajectory of the particles inside these devices to produce the required shape according to the function of the corresponding device and focuses the beam. The technical result is the possibility of rotating the beam through large angles without loss of intensity, significantly simplifying the design, and also reducing the mass and dimensions of all the devices, particularly by obviating the need for magnets and supply voltage and control voltage sources for such devices.
Abstract:
A compact, small foot print, light source based on electron beam acceleration for insertion devices in EUV range metrology and actinic mask inspection using coherent scattering methods includes spiral storage rings providing plane straight sections. A magnet structure generates emittance for brilliance and coherent light content. A booster feeds the storage ring by top-up injection and keeps electron beam intensity stable. A booster level below the storage ring receives the electron beam from a linear accelerator in a central booster area. The source fits into laboratories or maintenance areas. Injection, RF-acceleration, beam manipulating devices and large diagnostics systems are required once. Higher average currents stored in the spiral enhance central cone power. Bunches are limited by ion trapping and a gap clears ions. The current is increased in the spiral. Gain in central cone power increases 5 fold, assuming a gap size of half single storage ring circumference.
