WR1.00001: Applied Spectroscopy in Pulsed Power Plasmas Invited Speaker: Applied spectroscopy is a powerful diagnostic tool for high energy density plasmas produced with modern pulsed power facilities. These facilities create unique plasma environments with a broad range of electron densities (10$^{13}$ -- 10$^{23}$ cm$^{-3})$ and temperatures (10$^{0}$ -- 10$^{3}$ eV) immersed in strong magnetic (up to 10 T) and electric (up to 1 GV/m) fields. This paper surveys the application of plasma spectroscopy to diagnose a variety of plasma conditions generated by pulsed power sources including: magnetic field penetration into plasma, measuring the spatial distribution of 1 GV/m electric-fields, opacity measurements at stellar interior conditions, characteristics of a radiating shock propagating at 330 km/s, and determination of plasma conditions in imploded capsule cores at $\sim $150 Mbar pressures. These applications provide insight into fundamental properties of nature in addition to their importance for addressing challenging pulsed power science problems. [Preview Abstract] |
