    Abstract: 本发明涉及包括用于定向带电粒子、实现其加速和交互、以及产生由其运动引起的辐射的手段(即,用于改变加速带电粒子束的方向的方法、用于实现所述方法的设备)、波荡器电磁辐射源、带电粒子的线性和循环加速器、以及对撞机和用于产生由加速带电粒子流创建的磁场的装置的组。该方法以及实现该方法的设备基于对用于传送粒子的由能够充电的材料制成的弯曲通道(1)的使用、以及与粒子种类相同的电荷在通道内表面上的形成。这些发明的特征在于,它们需要维持使粒子的能量和电荷与通道的几何参数(特别是其纵轴(14)的曲率半径R)以及壁材料的电气强度相关的条件。该组中的其他设备包括用于改变射束方向的设备,该设备根据相应设备的功能将粒子的轨迹限定在这些设备内部以产生所需形状,并且使射束聚焦。技术效果是有可能具体地通过消除对磁体以及这些设备的电源电压源和控制电压源的需求来在不损失强度的情况下使射束旋转大角度、显著地简化设计、以及同时减小所有设备的质量和尺寸。

    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 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.
