Abstract: The invention comprises an X-ray tomography method and apparatus used in conjunction with multi-axis charged particle or proton beam radiation therapy of cancerous tumors. In various embodiments, 3-D images are generated from a series of 2-D X-rays images; the X-ray source and detector are stationary while the patient rotates; the 2-D X-ray images are generated using an X-ray source proximate a charged particle beam in a charged particle cancer therapy system; and the X-ray tomography system uses an electron source having a geometry that enhances an electron source lifetime, where the electron source is used in generation of X-rays. The X-ray tomography system is optionally used in conjunction with systems used to both move and constrain movement of the patient, such as semi-vertical, sitting, or laying positioning systems. The X-ray images are optionally used in control of a charged particle cancer therapy system.

Abstract: This invention relates to a type of cold cathode electron gun. On the base a cold cathode made of cold cathode material is mounted. Above the cold cathode, there is a grid gate electrode. Above the gate electrode, there is a focusing electrode with round aperture. The above electrodes are insulated from each other by installing on the insulating base through supports. A grid screening electrode can be added above the focusing electrode. The screening electrode is fastened to the base by the support for screening electrode. The use of screening electrode depends on the application occasions. In small device such as light element, the screen electrode is needed, while in lighting source, the screening electron may not be necessary. The cold electron gun described in this invention has simple structure, high performance. It can be used in electron source, cold cathode lighting source and lighting element. It also can be used in occasions with similar requirements.

Abstract: An electron beam generating section of an electron gun assembly includes at least a cathode that emits an electron beam, and a control electrode that is disposed on a phosphor screen side of the cathode. The cathode has a cathode face that is opposed to the control electrode, the cathode face having a concave shape with a recessed central portion. The electron beam that is emitted from the cathode face forms a cross-over with a tube axis. A cross-over point of an electron beam, which is emitted from the central portion of the cathode face, differs from a cross-over point of an electron beam, which is emitted from an off-axis portion of the cathode face.
