Abstract
Absorption spectroscopy has been used in this work to diagnose the conditions in the pusher of laser-imploded targets. Absorption lines are produced when continuum radiation from the hot central compressed gas passes out through the colder surrounding pusher. They can be used to determine both the temperature and the ρ ΔR product of the pusher around peak compression. Fair agreement is found between the experimental absorption spectra and simulations calculated by a hydrodynamic code. Applications of this work to the diagnosis of future, high-compression implosions is discussed.Keywords
