个人简介  

教育背景:

2010.092014.07: 西安交通大学 本科 专业:核工程与核技术

2014.092016.12: 国防科学技术大学 硕士 专业:物理学 研究方向:辐射流体

2017.092021.02: 曼彻斯特大学 博士 专业:物理学 研究方向:激光等离子体辐射源

主要研究内容:

1. 通过延迟的双束对撞激光照射固体靶产生增强的g 2017.9-2018.7

提出使用一定延迟的双束对撞激光照射固体靶。一束激光加热靶,在其背后形成较高密度的电子层,通过使用第二束激光和获得的稠密电子区域对撞,可以获得较高密度的g光。

2. 激光倾斜照射固体靶产生的稠密g光产生      2018.5-2018.10

通过把激光斜入射在固体靶表面,靶表面的电子被拉出并加速到GeV. 这些高能电子串在激光场中振荡,产生平均能量为12 MeV的稠密g光。

3QED机制下激光和电子的碰撞       2018.10-2019.3

研究了超强激光和相对论电子束的碰撞过程中光子和正电子的产生。讨论了碰撞角度、激光强度和电子能量对光子和正电子的能谱和产额的影响。

4. 超强激光和微结构靶相互作用中光子和正电子的产生 2019.3-2019.7

使用凹面靶代替一般的平面靶,然后用相对论激光照射。模拟显示这种结构可以明显的聚焦激光束并获得增强的激光场。这种增强的激光场可以拉出更多的表面电子,并且促进了g光的产生。另外,还研究了超强激光和微通道靶的相互作用。

5. 两束连续激光脉冲照射近临界密度等离子体产生的类同步辐射的高能g       2019.7至今

探索了双束相对论激光脉冲入射到近临界密度等离子体中,等离子体电子的行为。模拟中观察到由于特殊的激光场调制引起的稠密电子串被激光场俘获。这些电子串在激光场中振荡产生高密度的g光。
