This paper introduces the studies of the ultra-short Thomson scattering X-ray source at the accelerator laboratory of Tsinghua University in recent years. Properties such as the photon yield,the pulse length and time jitter of the produced photon pulse were predicted theoretically from the parameters of the electron bunch and the laser pulse,and the scattering angle. Preliminary experiments were successfully carried out with a 16 MeV backward-traveling-wave accelerator and the ns-Q switched laser provided by China Academy of Engineering Physics. This paper also introduces the 1.6-cell electron gun that was fabricated on site and the experiment with high RF power including the measurement of the electron bunche parameters. Based on these,we have designed an X-ray source,which is now under construction.

介绍了清华大学加速器实验室近年来关于汤姆逊散射超短X射线源的研究工作；研究了在任意散射角度下电子束参数和激光束参数对散射光子参数的影响，给出了散射光子的参数如光子产额、脉冲长度、时间抖动等与电子束参数、激光束参数和散射角度的关系；利用实验室已有的16 MeV反波行波加速器与中国工程物理研究院激光聚变研究中心提供的ns调Q激光搭建了汤姆逊散射初步实验平台并开展了实验研究；加工了1.6-cell光阴极微波电子枪，搭建了高功率实验平台，对产生的电子束参数进行了初步测量；对汤姆逊散射超短X射线源进行了设计并开展了相关的平台建设工作，对产生的X射线脉冲参数进行了模拟。

Rutherford and Teller were both immigrants who became fiercely patriotic in defense of their adopted countries. Both often behaved like overgrown children, losing their tempers over trivialities and then regaining their equilibrium with a friendly smile. Both were father figures to their students, taking care of students' personal problems as well as their professional education. Both were more interested in the strategy of science than in the tactics. Rutherford made the decision to explore nuclei with an accelerator, and then left the details of the accelerator to Cockcroft and Walton. Teller made the decision to build a hydrogen bomb or a safe reactor and then left the details to others. Both had a lifelong dedication to science, but spent more time helping younger people than doing research themselves. Teller published his version of the hydrogen bomb story under the title The Work of Many People. The names of Cockcroft and Walton appear on the letter to Nature announcing their discovery but Rutherford's does not. My name appears on the patent for the safe reactor but Teller's does not.

卢瑟福和泰勒都是移民，都对维护他们移民去的国家表示出狂热的爱国主义情绪；两者的行为都很像身体过度发育的孩子，对琐事大发雷霆，随后又若无其事，友好亲切；两者都对学生像父亲一样，既关心他们的个人问题，也关心他们的学业；两者都多科学研究的策略而不是技巧更感兴趣，卢瑟福决定用加速器研究原子，把有关加速器的细节问题留给卡斯喀特和华尔顿，泰勒决定造氢弹和安全反应堆，然后把细节问题留给其他人；两人都把一生献给科学研究，但花费在帮助年轻人的时间比自己做研究的时间要多得多；泰勒以《齐心协力》为标题讲述了他眼中的氢弹故事；卡斯喀特和华尔顿的名字出现在写给《自然》杂志宣布他们发现的信中，但信中没有卢瑟福的名字，我的名字出现在安全反应堆专利中，但也没有泰勒的名字。
