Laser guiding in a 33mm, 1GeV capillary discharge laser plasma accelerator

POSTER

Abstract

Recently, 1 GeV monoenergetic electron beams were generated in a capillary discharge laser plasma wakefield accelerator (LWFA), by using a capillary with a 312 micron diameter and 33 mm length. We will present analysis of the guiding properties of the capillary discharge waveguide, both at low and high ($3\ 10^{18} W/cm^2$) intensities. Measurements to diagnose the guiding structure will be discussed, including energy transmission, mode profile and transmitted laser spectrum.
