The generation of laser produced proton and ion beams is still under heavy investigation. Especially the acceleration of protons from the rear side of the target by an electrostatic field is due to their unique beam properties and various possible applications a topic of research activities.
Experiments with structured targets are a powerful tool to diagnose the properties of the electron sheath,the acceleration mechanism at very early times and proton beam parameters.
In this talk we will introduce an analytic model to describe the properties of the electron sheat and their influence to the spatial ion beam distribution. This model was supported by detailed simulations.
We also present beam parameters like source size, emmitance and energy distribution for a wide range of laser parameters.
