Discharge Lamp Oven


Research group Elementary Processes of Gas discharges, Professor G. Kroesen, PhD, department Applied Physics TU/e


Oven in which a plasma tube can be brought to a temperature of between 50 and 300° C by infrared radiation. The light transmitted by the plasma tube alters with the temperature. The composition of the plasma is measured by laser absorption as a function of temperature and radial position in the tube. For the purpose of this measurement the heart of the plasma tube must remain in position to within 0.1 mm.


  • Temperature max. 300 °C
  • Temperature variation ±3 °C over the entire length of the plasma tube
  • Position stability of the heart line of the plasma tube 0.1 mm
