Abstract

We developed a compact laser electron source which can be used as an X-ray source for nondestructive diagnosis instead of radio isotopes. High energy electrons were generated by an ultrashort laser pulse focused on a thin tape target. The laser energy was only 15 mJ. Pulse duration and beam diameter of the laser beam were 140 fs and 10 mm, respectively. We got over 1 MeV energetic electrons with this compact laser electron source.
