Generation of directed electron beams by tight focusing of an ultrashort IR laser in a near-critical plasma

Marianna Lytova, François Fillion-Gourdeau, Simon Vallières +4

Recent studies have demonstrated the possibility of accelerating electrons to MeV energies in ambient air using tightly focused laser configurations. In this article, we explore po…

Single shot phase contrast imaging using laser-produced Betatron x-ray beams

S. Fourmaux, S. Corde, K. Ta Phuoc +8

Development of x-ray phase contrast imaging applications with a laboratory scale source have been limited by the long exposure time needed to obtain one image. We demonstrate, usin…

Demonstration of the synchrotron-type spectrum of laser-produced Betatron radiation

S. Fourmaux, S. Corde, K. Ta Phuoc +10

Betatron X-ray radiation in laser-plasma accelerators is produced when electrons are accelerated and wiggled in the laser-wakefield cavity. This femtosecond source, producing inten…
