Gas Discharge Physics Laboratory
Responsible contact person: Kinga Kutasi (kutasi.kinga@wigner.mta.hu)
The Gas Discharge Physics Laboratory operated by the Gas Discharge Physics research group is the experimental basis for the research on the elementary processes in gas discharge plasmas. Currently four experimental units equipped with modern vacuum technology and plasma diagnostics serve the researchers. We have the possibility to:
- Investigate the effect of individual atomic collisions by means of emission and absorption spectroscopy
- Determine the electric characteristics of discharges with custom electrode configurations in a wide frequency range of the feeding power input from d.c. to radio frequency.
- Conduct research on dusty plasmas, where microscopic solid grains are immersed into a gas discharge plasma, with video microscopy and particle tracking velocimetry.
- Investigate the mechanism and effect of plasma treatment of solid samples in wide pressure and temperature ranges.
Services provided by the research laboratory:
- Generation of low pressure gas discharge plasmas in a wide variety of gases and range of pressure and excitation frequency
- Emission spectroscopy of gas discharges
- Absorption spectroscopy of gas discharges
- Electric characteristic measurements of gas discharges
- Breakdown characteristics measurements of gas discharges
- Creation and video microscopy measurements of dusty plasmas
- Plasma treatment of conducting and dielectric samples with active and post-discharges
