3rd US-Japan Plasma Polarization Spectroscopy Workshop

Plasma Polarization Spectroscopy logo

The 1st US–Japan Workshop on Plasma Polarization Spectroscopy was held February 1–3, 1994, at Los Alamos National Laboratory, Los Alamos, NM. The second workshop was hosted by Kyoto University and convened January 26–28, 1998, in, Kyoto, Japan. The third workshop was held June 18–21, 2001, at Lawrence Livermore National Laboratory, Livermore, California, U.S.A.

The purpose of the workshop was to review the current and assess future applications of polarization spectroscopy as a diagnostic tool for fusion plasmas in MFE and ICF, for short-pulse laser-generated plasmas, Z-pinch produced plasmas, electron-ion beam interactions, and for astrophysical sources.

The workshop addressed both experimental and theoretical issues pertaining to the emission of polarized radiation from plasmas. Topics were:

  • A review of the plasma environments that create polarized ensembles of atoms, electrons, and ions resulting in polarized radiation
  • Diagnostic techniques for identifying polarized radiation and plasma processes creating polarized ensembles
  • Effects of magnetic and electric fields
  • Assessment of relevancy to fusion energy plasmas
  • A review of the current status of theories that describe the creation and destruction of ensembles of polarized atoms, electrons, and ions
  • Needs for atomic data for proper descriptions of plasma polarization phenomena.

Proceedings

The Proceedings of our workshop have been printed as a University of California Lawrence Livermore National Laboratory report. The .pdf file of the proceedings (ca 48 MB) is available for download.
