\begin{frame}{Status quo}%{Ausgangslage}

\begin{itemize}
 \item radio therapy is an important tool in cancer therapy
 \item continuous development towards improved tolerability and increase of the therapeutic window

 \item two promising developments in recent years:
 \begin{itemize}
  \item encouraging results with very short, high dose beams (FLASH RT)
  \item recent further development of spatially fractionated RT towards Microbeam Radiation Therapy (MRT)
 \end{itemize}
\item both show improved sparing of healthy tissue and reduction of secondary cancer also increasingly important due to increase in overall life expectancy
\item both are dependent on the use of particle accelerator facilities
\begin{itemize}
 \item for FLASH: to achieve the required intensity in short pulses, e.g. linear accelerators for electron RT
 \item for MRT: in case of x-ray beams, a high brilliant synchrotron light sources are required to provide sufficiently parallel propagating micro beams
\end{itemize}
\item very high requirements on stability and metrology of the used beams
\end{itemize}

\begin{frame}{Motivation for the research group}

The present advances in accelerator based RT, like FLASH RT or micro beam RT,
lead to operation parameters of the used accelerators that can not anymore be described by simple linear optics and beam dynamics. Instead, due to the development towards higher intensity combined with shorter pulse lengths and transverse modulations, the consideration of nonlinear and complex optics as well as beam dynamics influenced by collective effects becomes necessary.\\

Helping to bridging this gap between accelerator science and medical physics from the accelerator side is an important step and will help in paving the way towards the application of...
% aims to greatly improve the applicability of these RT methods in the future.

 \item start with simulations on the 3D charge distribution expected at the exit of the linear accelerator
 \item followed by simulation of the beam dynamics for this charge distribution on its trajectory to the target
 \begin{itemize}
  \item based on existing simulation tools and models
  \item based on existing beam-matter interaction descriptions
