    • PROBLEM TO BE SOLVED: To provide an X-ray generator having high reliability over a long period of time.SOLUTION: An X-ray generator includes: a high voltage connector 2; an X-ray tube 1; a fixing member 5; and a spring. The high voltage connector 2 includes an electrical insulating material having an end surface S22 formed thereon, and a high voltage output terminal 23. The X-ray tube 1 includes a high voltage input terminal 14, a high voltage insulating part in which an adhering surface S13 adhered directly or indirectly to the end surface 22 is formed, and a gap forming surface S11. The fixing member 5 has the gap forming surface S5, and is fixed directly or indirectly to the high voltage connector 2. The spring is in contact with the gap forming surface S11 and the gap forming surface S5.

    • PROBLEM TO BE SOLVED: To provide an X-ray tube electron source which is relatively inexpensive and extended in life.SOLUTION: An X-ray tube includes an emitter wire (18) enclosed in a suppressor (14, 16). An extraction grid includes a number of parallel wires (20) extending perpendicular to the emitter wire, and a focusing grid includes a number of wires (22) parallel to the grid wires (20) and spaced apart at equal spacing to the grid wires (20). The grid wires are connected by means of switches to a positive extracting potential or a negative inhibiting potential, and the switches are controlled so that at any one time a pair of adjacent grid wires (22) are connected together to form an extracting pair, which produces an electron beam. The position of the beam is moved by switching different pairs of grid wires to the extracting potential.
    • 要解决的问题:提供相对便宜并延长寿命的X射线管电子源。 解决方案:X射线管包括封闭在抑制器(14,16)中的发射极线(18)。 提取栅格包括垂直于发射极线延伸的多条平行线(20),并且聚焦栅格包括平行于栅格线(20)并以等间距与网格线间隔开的多条线(22) 20)。 电网线通过开关连接到正提取电位或负抑制电位,并且开关被控制,使得在任何一个时间将一对相邻格栅线(22)连接在一起以形成提取对,其中 产生电子束。 通过将不同的栅格线对切换到提取电位来移动光束的位置。 版权所有(C)2012,JPO&INPIT
