Spectroscopic measurements of the Laser-HANE plasma
Abstract
To simulate HANE phenomena at various altitudes, a pulsed (5 nsec) Nd-laser is focused onto Al or C foil targets surrounded by an ambient gas (N2, H2) at pressures between 15 m Torr and 5 Torr. Temperatures and densities are derived from side-on, time-resolved and time-integrated measurements of absolute spectral line and continuum intensities emitted from the photoionized region ahead of the blast-wave front, and also in the region behind the blast front.
