Experimental investigations of the plasma potential and electric field were performed for ELMy H-mode plasmas in the vicinity of the limiter shadow of ASDEX Upgrade. A fast reciprocating probe with a probe head containing four ball-pen probes (BPPs) [J. Adamek et al., Czech. J. Phys. 54 (2004) C95 – C99.] was used on the midplane manipulator. Different gradients of the plasma potential were observed during ELMs and in between them. The temporal resolution of the direct plasma potential measurements with BPP was determined by using power-spectra analysis.
Studium potenciálu plazmatu a elektrického pole bylo provedeno během ELMy H-módu na tokamaku ASDEX Upgrade v v blízkosti stínu limiteru. Byla použita sondová hlavice obsahující čtyři ball-pen sondy, které byly umístěny na rychlém reciprokujícím manipulátoru. Byly pozorovány různé gradienty potenciálu plazmatu během ELMů a mimo ně. Časové rozlišení měření bylo stanoveno pomocí power-spectra analýzy.
