摘要： An X-ray source and a corresponding method for generating X-ray radiation are disclosed. The X-ray source includes a chamber comprising an interaction region, and a first electron source operable to emit a first electron beam, including electrons of a first energy, towards the interaction region such that the first electron beam interacts with a target to generate X-ray radiation. The X-ray source further includes a second electron source adapted to be independently operated to emit a second electron beam including electrons of a second energy for ionising particles in the chamber, and an ion collection tool that is adapted to remove the ionised particles from the chamber by means of an electromagnetic field. By ionising particles and preventing them from moving freely in the chamber, problems related to contamination of the chamber may be mitigated.

摘要： The present invention relates to an X-ray tube with non-evaporable getters disposed therein for maintaining a degree of vacuum sufficient to operate the X-ray tube. The present invention provides a fixed-anode X-ray tube and a rotating-anode X-ray tube in which non-evaporable getters are disposed. The X-ray tubes, even when rated power is introduced without an aging process, can perform gas adsorption sufficiently and stably during operation, despite gases that can be generated by the filament and the cathode focusing cap and gases that can be generated by the target.

摘要： A gamma ray generator includes an ion source in a first chamber. A second chamber is configured co-axially around the first chamber at a lower second pressure. Co-axially arranged plasma apertures separate the two chambers and provide for restricted passage of ions and gas from the first to the second chamber. The second chamber is formed by a puller electrode having at least one long channel aperture to draw ions from the first chamber when the puller electrode is subject to an appropriate applied potential. A plurality of electrodes rings in the third chamber in third pressure co-axially surround the puller electrode and have at least one channel corresponding to the at least one puller electrode aperture and plasma aperture. The electrode rings increase the energy of the ions to a selected energy in stages in passing between successive pairs of the electrodes by application of an accelerating voltage to the successive pairs of accelerator electrodes. A target disposed co-axially around the plurality of electrodes receives the beam of accelerated ions, producing gamma rays.

摘要： The invention is directed to a process for making screen-printable getter composition comprising: (a) glass frit; and (b) pre-hydrated desiccant material; dispersed in (c) organic medium. The present invention further relates to a getter composition utilizing low-softening temperature glasses comprising, based on weight %, 1-50% SiO2, 0-80% B2O3, 0-90% Bi2O3, 0-90% PbO, 0-90% P2O5, 0-60% Li2O, 0-30% Al2O3, 0-10% K2O, 0-10% Na2O, and 0-30% MO where M is selected from Ba, Sr, Ca, Zn, Cu, Mg and mixtures thereof. The glasses described herein may contain several other oxide constituents that can substitute glass network-forming elements or modify glass structure.The desiccant material is pre-hydrated to reach its saturation level of moisture absorption. The process of pre-hydration can be done by exposing the desiccant in a normal temperature/humidity environment of for example, 25° C. and 50-60% RH. For 24 to 48 hours or up to the time when weight gain (due to moisture absorption) stops increasing. An accelerated hydration process in a chamber with higher than normal humidity level (i.e. 50% Relative Humidity) is also applicable to shorten the time of exposure to fully hydrate the desiccant material.

摘要： The present invention relates to applying an existing carbon nanotube X-ray tube for a dental X-ray imaging system that can replace a carbon nanotube electron emission source installed in a cathode portion. An X-ray tube system formed in a pen according to the present invention can be inserted in the oral cavity due to its thin thickness, thereby displaying an accurate image of an inner location of the oral cavity needing a diagnosis. For therapy of oral cancer requiring an appropriate amount of radiation therapy, since radiation can be directly irradiated to a diseased part, brachytherapy is enabled without concern of exposure dose of normal tissues. Therefore, when the system is commercialized, a great amount of distribution effect may be expected. The X-ray tube system that can be used for medical services such as a dental service includes an X-ray emission module emitting X-rays using a chipped nano-structured material, for example, carbon nanotube. The X-ray emission module is separable from a body in order to replace a cathode portion that is included in the X-ray emission module and is based on the nano-structured material.
摘要翻译：本发明涉及应用现有的用于牙科X射线成像系统的碳纳米管X射线管，其可以替代安装在阴极部分中的碳纳米管电子发射源。根据本发明的用笔形成的X射线管系统由于其厚度薄而能够插入口腔，从而显示需要诊断的口腔内部位置的精确图像。对于需要适量辐射治疗的口腔癌的治疗，由于辐射可以直接照射到患病部位，所以可以进行近距离放射治疗而不考虑正常组织的暴露剂量。因此，当系统商业化时，可以预期大量的分配效应。可用于医疗服务如牙科服务的X射线管系统包括使用切片纳米结构材料（例如碳纳米管）发射X射线的X射线发射模块。为了更换X射线发射模块中包含的阴极部分并且基于纳米结构材料，X射线发射模块可与主体分离。
