摘要:

质子照相诊断技术广泛应用于激光等离子体实验中的磁场测量。分析的最新发展使路径集成磁场值的定量重建成为可能,但对磁场的三维结构做出结论仍然具有挑战性。在这封信中,我们提出并证明了一种新的目标几何形状的动力学模拟,使生产多个质子束从一个单一的激光脉冲,使应用断层成像方法的质子射线照相。

英文摘要:

The proton radiography diagnostic is widely used in laser-plasma experiments to make magnetic field measurements. Recent developments in analysis have enabled quantitative reconstruction of path-integrated magnetic field values, but making conclusions about the three-dimensional structure of the fields remains challenging. In this Letter we propose and demonstrate in kinetic simulations a novel target geometry which makes possible the production of multiple proton beams from a single laser pulse, enabling the application of tomographic methods to proton radiography.
