摘要

At the GOL-3 facility, experiments on the interaction of powerful hot electron streams with various materials have been performed. For energy densities of the hot electron stream above 10 MJ/m~2 an explosive-like erosion was observed, which at energy densities of 30 MJ/m~2 reaches 500 μm for fine grain graphite and 200 μm for tungsten. Under these conditions, the corona of the carbon vapour cloud has temperatures below 1.2 eV and densities up to 10~17 cm~-3. It propagates along the magnetic field lines with maximum velocities of 2.7 × 10~6 cm/s. The longitudinal and transverse (along and across magnetic field lines) vapour velocities of the colder bulk plasma are about 10~6 cm/s.
