Relativistic electrons from vacuum laser acceleration using tightly focused radially polarized beams
Jeffrey Powell, Spencer W. Jolly, Simon Vallières +7
We generate a tabletop pulsed relativistic electron beam at 100 Hz repetition rate from vacuum laser acceleration (VLA) by tightly focusing a radially polarized beam into a low-den…
