Title
(EN) COLD CATHODE X-RAY TUBE AND CONTROL METHOD THEREFOR
(ZH) 冷阴极型X射线管及其控制方法
Abstract
(EN) Provided is a cold cathode X-ray tube capable of preventing time-dependent decrease in anode current such that the cold cathode x-ray tube stably operates for a long period of time. A cold cathode X-ray tube (1) comprises: an electron discharge portion (10) including an electron discharging element using a cold cathode; an anode portion (11) disposed so as to be opposed to the electron discharge portion (10); a target (12) disposed on a part of the surface of the anode portion (11); a casing (15) in which the electron discharge portion (10), the anode portion (11), and the target (12) are disposed; and a hydrogen generation portion (14) made of material that generates hydrogen when electrons collide therewith and disposed at a part of the surface present inside the casing (15) other than the surface of the target (12).
(ZH) 提供冷阴极型X射线管,通过防止阳极电流随时间的降低,能够长时间地进行稳定驱动。冷阴极型X射线管(1)具有:电子发射部(10),其包含使用了冷阴极的电子发射元件;阳极部(11),其与电子发射部(10)对置地配置;靶(12),其配置于阳极部(11)的表面的一部分;壳体(15),其在内部配置有电子发射部(10)、阳极部(11)以及靶(12);以及氢产生部(14),其由当与电子碰撞时会产生氢的材料构成,并且配置于存在于壳体(15)的内部的表面中的除靶(12)的表面以外的部分。
