Impact of Residual Angular Chirp in a Petawatt-class Laser System on Laser-driven Proton Acceleration
Qingfan Wu, Minjian Wu, Jiarui Zhao +25
The paper shows that a small residual angular chirp caused by misaligned grating compressors in a petawatt laser degrades the focal spot and reduces proton energies, and that remov…

Electron acceleration and X-ray generation from near-critical-density carbon nanotube foams driven by moderately relativistic lasers
Zhuo Pan, Jianbo Liu, Pengjie Wang +21
Direct laser acceleration of electrons in near-critical-density (NCD) carbon nanotube foams (CNFs) has its advantages in the high-efficiency generation of relativistic electrons an…
