Comparison of fluctuations properties measured by Langmuir and by ball-pen probes in the ISTTOK boundary plasma

Popis výsledku v původním jazyce

Langmuir probes (LPs) are extensively used in the boundary of fusion devices providing most of the data on the local electron temperature, potential and plasma density. They allow the simultaneous determination of several plasma parameters with high spatial and temporal resolution justifying its continued use, particularly for turbulent transport studies. Neglecting the influence of the electron temperature fluctuations. This approach is often questioned as the properties of the floating and plasma potential fluctuations appear to be significantly different. Recently, ball-pen probes (BPPs) were found to be well-suited for routine measurements of the plasma potential in the edge plasma of fusion devices. Different probe systems combining LP and BPPs has been developed on ISTTOK to simultaneously measure the floating and plasma potential, permitting also the determination of the turbulent particle flux using both types of probes.
