\item[Can I import an electric field from TCAD and use it for simulating propagation?]
Yes, the framework includes a tool to convert DF-ISE files from TCAD to an internal format which \apsq can parse.
More information about this tool can be found in Section~\ref{sec:tcad_electric_field_converter}, instructions to import the generated field are provided in Section~\ref{sec:module_electric_field}.
\item[What parameters should I consider when writig a simulation for a non-silicon sensor?]
While \apsq implements several material-dependent default parameters, other parameters and models default to values suitable for silicon sensors.
It is in any case advisable to check the following configuration parameters to ensure consistent results.
\begin{itemize}
\item Sensor material: The parameter \parameter{sensor_material}, to be adjusted in the corresponding detector model file, is crucial for the particle interaction simulated via Geant4 and defines further default parameters.
\item Charge creation energy: The parameter \parameter{charge_creation_energy} is available in several modules for energy deposition and provides a material dependent default. For default values see Section~\ref{sec:material_properties}.
\item Fano factor: The parameter \parameter{fano_factor} is available in several modules for energy deposition and provides a material dependent default. For default values see Section~\ref{sec:material_properties}.
\item Mobility Model: The \parameter{mobility_model} needs to be adapted to the sensor material by the user. Section~\ref{sec:mobility} lists the available models.
\item Recombination Model: Accessible via the parameter \parameter{recombination_model}, available models are listed in Section~\ref{sec:mobility}.
When adding a new sensor material, additions at several positions in the code are necessary:
\begin{itemize}
\item Add material to list of available sensor materials in \command{src/core/geometry/DetectorModel.hpp}
\item If not available yet, add material to the Geant4 material manager (\command{src/modules/GeometryBuilderGeant4/MaterialManager.cpp}). See examples of either using a material known to Geant4 or defining compositions in the code. It should be noted that the key of the \parameter{materials_} map needs to match the name of the sensor material defined in the previous step, transformed to lower case letters.
\item Define default values for the material properties listed in \command{src/physics/MaterialProperties.hpp}.
\item Add the list of material properties to the corresponding section of the user manual: \command{doc/usermanual/chapters/models.tex}.
\end{itemize}
Any contribution to the framework in terms of new sensor material definitions is welcome and can be added via a dedicated merge request.
