    • An electron therapy unit for delivering therapeutic electrons to a patient during an operation that is made up of a movable and stowable beam head that may be connected permanently or temporarily to either a base cabinet or a fixed structure using one or more optionally pivotable arms is provided. In an exemplary embodiment, the inventive electron therapy unit is a mobile unit suitable for in-hospital use or for shared use between hospitals or clinics. The unit is self-contained, small, light and easy to use. It has a very reliable, compact design, allowing for easy stowing to a small rugged configuration for transport. In another exemplary embodiment, the inventive electron therapy unit is a stationary unit. An ion chamber for use with such an optionally transportable electron therapy unit is also provided. The ion chamber employs two or more collector plates and associated bias plates, each having a centrally located hole that extends through the plate. Further provided is a method for reducing or eliminating the possibility of significantly higher current caused by electrical arcs and power excursions during operation of the inventive electron therapy unit.
    • 提供了一种电子治疗单元,用于在由可移动和收起的血束头组成的操作期间将治疗电子递送到患者,该头部可以使用一个或多个可选择地枢转的臂永久地或临时地连接到基部柜或固定结构, 。 在示例性实施例中,本发明的电子治疗单元是适于在医院或医院或诊所之间共同使用的移动单元。 该设备是独立的,小巧轻便易于使用。 它具有非常可靠,紧凑的设计,可以方便地装载到一个小的坚固的配置上进行运输。 在另一示例性实施例中,本发明的电子治疗单元是固定单元。 还提供了一种与这种可选择地可移动的电子治疗单元一起使用的离子室。 离子室采用两个或更多个集电板和相关的偏置板,每个偏置板具有延伸穿过板的中心定位的孔。 还提供了一种用于减少或消除在本发明的电子治疗单元的操作期间由电弧和功率偏移引起的显着更高的电流的可能性的方法。

    • A microwave system for driving a linear accelerator is provided. The inventive microwave system employs a plurality of magnetrons, at least one pulse generator to energize the magnetrons, means for synchronizing outputs from the magnetrons, and at least one waveguide for transmitting synchronized outputs or power from the magnetrons to a linear accelerator. The linear accelerator that is driven by the inventive microwave system demonstrates increased efficiency and dependability, higher energy and power outputs, as well as, different energy outputs that can take the form of successive pulses that alternate between at least two different energy levels.
    • 提供一种用于驱动线性加速器的微波系统。 本发明的微波系统采用多个磁控管,至少一个脉冲发生器来激励磁控管,用于同步来自磁控管的输出的装置,以及用于将来自磁控管的同步输出或电力传输到线性加速器的至少一个波导。 由本发明的微波系统驱动的线性加速器表现出提高的效率和可靠性,更高的能量和功率输出,以及可以采取在至少两个不同能级之间交替的连续脉冲形式的不同能量输出。
