Abstract

We present a novel scheme for rapid quantitative analysis of debris generated during experiments with solid targets following relativistic laser-plasma interaction at high-power laser facilities. Results are supported by standard analysis techniques. Experimental data indicates that predictions by available modeling for non-mass-limited targets are reasonable, with debris on the order of hundreds μ-per-shot. We detect for the first time two clearly distinct types of debris emitted from the same interaction. A fraction of the debris is ejected directional, following the target normal (rear- and interaction side). The directional debris ejection towards the interaction side is larger than on the side of the target rear. The second type of debris is characterized by a more spherically uniform ejection, albeit with a small asymmetry that favours ejection towards the target rear side.
