\def\GWslide{\slide{Available topics}{
\begin{itemize}
\item Level 0 "a game/playground"
\item Level 1 "basic"
\begin{itemize}
\EduTopic{Breakdown studies}{Investigate probability of the plasma breakdown (creation of plasma), mainly the role of the working gas (Hydrogen or Helium) and its pressure $p_{WG}$, breakdown electric field controlled by the $U_{E_t}$ and its orientation. A dependency similar to the Paschen Curve \cite{chen2015introduction} can be obtained.}{}
\EduTopic{Energy confinement time $\tau_E$}{Under the assumption of a simplified power balance, the  heating power $P_H$ is partially absorbed in the plasma and leads to an increase of the plasma energy $W_p$ and the rest is lost as the loss power $P_L$. The energy confinement time is defined as the characteristic time scale of the exponential decay of the plasma energy $W_p$ due to the loss power $P_L$. Choosing the quasistationary phase of the plasma discharge gives: $\tau_E(t)=\frac{W_{p}(t)}{P_H(t)}$}{}
\EduTopic{$\mathbf{q=2}$ disruptions}{When the plasma current $I_p$ grows so strong that the edge safety factor $q$, see \cite{Wesson:2004}, reaches the
value of 2, a plasma instability resonant to the q = 2 rational surface destabilizes, and a discharge
terminating disruption occurs. The aim is to reach this limit of tokamak operation.}{}
\end{itemize} 
\item Level 2 "data mining"
\begin{itemize}
\EduTopic{Neo-Alcator confinement scaling law}{To compare the plasma behaviour (in particular the confinement time) in the GOLEM tokamak with the so-called Neo-Alcator confinement scaling law, see \cite{Goldston_1984}.}{}
\EduTopic{Machine learning}{The large database of discharges with their associated breakdown success or disruption termination can be used to train machine learning algorithms to predict the breakdown \cite{MOdstrcil} or disruption probability.}{}
\end{itemize} 
\item Level 3 "advanced"
\begin{itemize}
\EduTopic{Isotopic studies}{Comparison of tokamak discharges in H$_2$ and He$_2$ working gas, for an exemplary report see \cite{Svoboda2016}. Differences between discharges (for example turbulence properties observed by probes) in H$_2$ and He$_2$ as the working gas can be analyzed and explained. Which plasma parameters are influenced by higher mass of the main species particles and which are influenced by much higher 
ionization energy of He can be also investigated.}{}
