Strong enhancement in proton energy was investigated from a two-dimensional particle-in-cell simulation where an ultraintense laser pulse irradiates a 2-μm thick metal foil coated with a low density, 1-μm thick PMMA (polymethylmathacrylate - C5H8O2

Modified calculation method using FFT filtering and reconstructing of an interferogram for monitoring a laser-plasma density

Autor: Kitae Lee, Young Uk Jeong, Seong Hee Park, Woo-Je Ryu, Jae Heung Jo

Publikováno v: Journal of the Korean Physical Society. 79:297-308

In a laser-plasma electron acceleration, the quality of electron beams is sensitive to the parameters of a laser and a plasma density. With a given laser, higher plasma density may be good for higher charge, while lower density is better for longer a

A laser-induced intense Ka hard X-ray source was developed by using a novel copper film target and a 27-TW femtosecond laser system. A specially designed pinhole camera was employed to measure the X-ray photon flux, X-ray energy spectrum, and X-ray s
