\begin{itemize}
    \item Definition of interface connectors.
        \begin{itemize}
            \item Is data interface separated from power interface?
            \item Preferred connector type and pinning?
            \item When non operational survival heater is needed, is this an individual connector?
            \item Our instrument has a high speed streaming calibration data interface, which is not connected to space craft on FM. We prefer to have this data lines on one of the existing connectors.
        \end{itemize}
    \item Input voltage range? We prefer 28V, what is the expected worst case input voltage range for our instrument?
    \item Current limiter? Is there a current limiter on space craft side or is there a maximum peak current requirement for our instrument, we have to take care of?

    \item Rad hard requirement? R-SC-AHEPaM-343:  Radiation design margin
    \item thermal environment - realistic scenario needed for further detailed studies
    \item several requirements need input from ESA:
    \begin{itemize}
        \item R-AHEPaM-021:  Proton precision
        \item R-AHEPaM-025:  Electron precision
        \item R-AHEPaM-026:  Electron precision
        \item R-AHEPaM-027:  Electrons statistical accuracy
        \item R-AHEPaM-030:  Helium relative precision
        \item R-AHEPaM-039:  Thermal limits
        \item R-AHEPaM-041:  AHEPaM TRP
        \item R-AHEPaM-042:  Radiative thermal IF
        \item R-AHEPaM-044:  Thermal stability
        \item R-AHEPaM-045:  Conductive IF stability
        \item R-AHEPaM-046:  Conductive IF temperature gradient
        \item R-AHEPaM-047:  AHEPaM mass
        \item R-AHEPaM-140:  Sine vibration
        \item R-AHEPaM-150:  Accoustic environment
    \end{itemize}
