\slide{Probe measurements @ tokamak GOLEM outcome}{
Conclusions:
\biftns
\im Discharges on the GOLEM tokamak are quite reproducible => IV characteristics of a single Langmuir probe can be
recorded on shot – to shot basis
\im Temporal evolution of the plasma parameters is determined with a high temporal resolution (~10 us)
\im Surprisingly, the whole IV characteristics are very well fitted by the empirical analytical expression proposed by
Azooz
\im Probe date are very well fitted by the empirical analytical expression proposed by
Azooz and the $T_e$ , $n_e$, $U_{pl}$ and the Electron Energy Distribution Function can be
determined
\biftns
\im Tokamak discharge – edge electron temperature ~ 10 eV, densities ~$10^{17}$ /m$^3$, Electron Energy Distribution
Function is Maxwellian
\im MW plasma used for breakdown: Electron temperature < 1 eV, plasma density ne ~ $10^{13}$ /m$^3$ after switching off the
MW power, plasma is confined in toroidal magnetic field for ~ tens of milliseconds, EEDF is Maxwellian
