Interaction of hot electron plasma with solids at the GOL-3 facility

The GOL-3-II facility was used for the investigation of the interaction of a high-power plasma stream with solids. The experiments allowed the study o f the properties of the dense plasma formed in front of materials under act ion of the fast electrons flowing out the open trap. Target plasma from ent rance foil with density 10(16)cm(-3) has the expansion velocity 2-4 10(6) c m/c. Explosive-like erosion of the exit graphite receiver was been observed . Formation of a dust cloud is a feature of this phenomenon. Properties of the dusty particles are discussed.
