Fast measurements of the electron temperature in divertor region of the COMPASS tokamak using ball-pen probe

Popis výsledku v původním jazyce

The electron temperature in divertor regions of present day devices is typically measured by swept Langmuir probes or triple probe technique. However, the measurement of its evolution during ELM filaments requires high temporal resolution, which has notbeen achieved by these techniques yet. Alternative option how to determine the electron temperature with high time resolution is to use direct measurements of the plasma and floating potentials. The electron temperature is consequently determined from the difference of both potentials normalized by the proper coefficient for specific gas and magnetic field. The floating potential is routinely measured by Langmuir probe and the plasma potential can be directly measured by ball-pen probe (BPP). Recently,a new array of BPPs and dome-shaped Langmuir probes was installed also in a divertor target of the COMPASS tokamak.
