    Study of magnetic field influence on charged species in a low pressure helicon reactor

  • Original language description

    The variation of electron density, ion flux and emission of argon lines were investigated in a rf helicon reactor for different static magnetic field amplitude and rf power using Langmuir probe, rf coupled planar probe and optical emission spectroscopy.The static magnetic field was created by two Helmholtz coils positioned around the plasma source. Its amplitude B varied by changing the current 0-2 A through the coils from 0 to 10 mT in the helicon source, which corresponded to 0-1.4 mT in the diffusion chamber. We studied Ar and O2 discharges at 0.7~Pa with rf power 50-600 W applied to the helicon antenna. The variations of electron density, ion flux and intensity of Ar 750~nm with the rf power measured in Ar diffusion plasma were in a good agreement. Measurements in oxygen discharge showed slightly different results.

    Studium vlivu magnetického pole na nabité částice v nízkotlakém helikonovém reaktoru

  • Czech description

    Studium koncentrace elektronů, toku iontů a emisní argonové čáry v vf helikonovém reaktoru pro různé statické magnetické pole. Použité metody: Langmuirova sonda, vf planární sonda a optická emisní spektroskopie. Statické magnetické pole bylo vytvářena dvěmy cívkami okolo zdroje jehož hodnota se pohybuje od 0 do 10 mT ve zdroji a mezi 0 a 1,4 mT v difúzní komoře. Byl studován argonový a kyslíkový výboj při tlaku 0,7 Pa a vf výkonu 50-600 W v helikonové anténě. Průběhy závislostí koncentrace elektronů, toku iontů a intenzity argonové čáry 750 nm na výkonu byly v dobré shodě. Měření v kyslíkovém výboji ukazuje lehce odlišné výsledky
