Abstract :
Using the upgraded Vulcan Petawatt laser at 3/spl times/10/sup 20/ Wcm/sup -2/ intensities, target interactions and acceleration in a gas jet were studied. Electron spectra with energies up to 240 MeV were detected. Indications of a new acceleration regime, which results in a nonMaxwellian distribution were observed.
