Description

We will give an overview of the latest commissioning status of the ATLAS-3000 laser system at CALA, before reviewing the main results from the laser-wakefield related campaigns with the predecessor 100-TW system. Quasi-monoenergetic shock-front accelerated electron bunches with energies up to 300 MeV and charge figures of >250 pC were routinely produced. The scaling of their spectral shape with injected charge shows clear signs of beamloading, and control over the injected charge could be achieved by modifying the laser field strength at the injection point. Shock-front injection was combined with beatwave-injection, which produced two independently energy-adjustable electron bunches, and the effect of beam-loading of the first bunch on the energy of the second bunch was observed. The high-charge LWFA bunches were used to drive plasma waves in a secondary plasma, and first experiments towards hybrid acceleration were performed. Single or multiple bunches were also used to generate Thomson-scattered photons employed in multi-color imaging experiments. Moreover, betatron radiation was used for fast tomography of a bone sample.
