Emission spectroscopy


  • Collect light from the experiment with spatial, temporal and spectral resolutions.
  • Enable light collections within a broad spectral range (visible, UV, Vacuum UV, x-UV, x-ray).
  • Maximize the light collection efficiency.


  • Use of different light collection systems - mirrors, lenses, beamsplitters, polarizers, optical fibers.
  • The light is dispersed using gratings (visible, UV, VUV), crystals (x-ray), or Ross filters (x-ray).
  • The light is detected using: photomultipliers or with time dispersers (streak cameras) coupled to CCD cameras.


  • Measurements of atomic and ionic spectral line emission from the x-ray to near IR wavelength range.
  • Application of polarization-dependent spectroscopy.
  • Determination of the non-equilibrium plasma conditions.
  • Measurement of the electromagnetic fields.


  • Non-intrusive measurements.
  • High spatial and temporal resolutions.
  • High spectral resolution and flexible spectral selectivity.

Applications in our laboratory

  • Experimental studies of the density, temperature and velocity distributions of atoms and ions including the charge-state distributions of different ions.
  • Investigations of electric and magnetic fields inside the plasma and their interaction with the non-equilibrium plasma.
  • Study of the onset of turbulence in current-carrying plasmas.
  • Study the physics of dense plasmas and their interaction with radiation.
