Abstract

A high power laser (TW) was used to accelerate electrons in a laser-driven wakefield accelerator. The high energy electrons were then used to generate an X-ray beam by passing them through a converter target.This bremsstrahlung source was characterised and used to perform penetrative imaging of industrially relevant samples. The photon spectrum had a critical energy in excess of 100 MeV and a source size smaller than the resolution of the diagnostic (≤150μm). Simulations indicate a significantly smaller source (
