Fast electron generation and transport in solid matter irradiated at relativistic intensities. Evidence of vxB acceleration
Abstract
In the context of the fast electron transport in solid matter and the fast ignitor scheme,we report on measurements of second harmonic of the laser light observed on the rear side of solid targets irradiated by the 100 TW laser at LULI. This emission can be explained by the acceleration of short bunches of electrons in the front of the target by the vxB force. The observations indicate that, in our conditions, the minimum fraction of the laser energy transferred to these electron bunches is of the order of 1 °.
