| 摘 要： | X光管是X射线源的关键部件,为了研制出便携式X射线标定源,研制了一种透射式X光管。该X光管是一个密封的电子束真空二极管,其阴极为竖直的梳齿状结构,电子更容易发射;靶窗为100μm厚的钛片;内部为真空腔,使用95陶瓷作为真空界面绝缘体,采用金属-陶瓷封接工艺,真空度达到5×10^-5 Pa。实验结果表明,所研制的X光管在距靶窗20 cm处剂量约为20 mR,此时X射线的脉冲宽度约为5 ns。

| Abstract: | The X-ray tube is a key component of an X-ray source.An X-ray tube used for a compact nanosecond pulsed X-ray source is described in this paper.The X-ray tube is a sealed transmission target X-ray diode.Its cathode is acomb structure formed from thin tungsten sheets with thickness of 50μm,while its target is made of a 100μm-thick titanium film.The X-ray dose at a distance of 20 cm from the diode is 20 mR per pulse while the diode voltage is 512 kV.In this case,the full width at half maximum of the X-ray pulse is about 5 ns. |
