Applications in our laboratory

  • Experimental studies of densities and velocity distributions of atoms and ions and of the charge state distributions in the plasma bulk and in the immediate vicinity of surfaces.
  • Investigations of the electric and magnetic fields both inside the plasma volume and in the sheaths
  • Plasma seeding technique development and investigation.
  • Investigation of various plasma-wall interactions, such as plasma formation in plasma sources, material ejection from surfaces into plasmas, plasma-assisted manufacturing, and plasma sheaths.

Measurements in our laboratory

  • Ion Diode experiments utilized LIF and Laser Absorption for plasma properties investigation: - plasma density, plasma temperature, particle velocities and charge state distribution.
  • POS experiments use LIF and Laser Absorption for the measurements of the local plasma parameters:
    • plasma density, plasma temperature, particle velocities and plasma composition;
    • measurements of local parameters and distributions of electric and magnetic fields in current carrying plasma;
    • development and characterization of novel plasma doping techniques fluorescence.
