However the initial \acs{TMM} \cite{ahepam-djf} shows, that the instrument design can be adapted in order to withstand the required hot op and non-op temperatures. The results indicate that the instrument might, besides its surfaces which will be used as radiators, require external radiators in the range of A$_{RAD}$=0.01..0.03$m^2$ assuming direct solar illumination at 1 AU.

\paragraph{Comments:} The required 5 energy bands for protons are driven by the need to sample the varying response of these particles to the Solar cycle as a function of energy. The division should roughly follow the energy distribution of primaries as estimated via simulations and should account for the fact that temporal variations are stronger at lower than at higher energies, see Sect. 5 of the TN for more details. An indicative break up of energy bands would be: 0.1-0.3, 0.3-0.6, 0.6-0.8, 0.8-1.0, 1.0-2.0 (all expressed in GeV). Cosmic-Ray protons feature a continuum spectrum which implies that small gaps or superpositions between adjacent energy bands do not constitute a problem. \paragraph{Comments:} The required 5 energy bands for protons are driven by the need to sample the varying response of these particles to the Solar cycle as a function of energy.

The performance analysis has shown that \ac{AHEPaM} will be able to measure protons over the entire required energy range. The amount of energy bands we can provide is only limited by statistics. The data is required to be send down at higher cadence and energy resolution not only to provide an accurate proton spectrum but for the purpose of correcting the electron spectrum.

Neutrons deposit mostly their energy in the hydrogen rich BC-412 plastic scintillator while the heavy inorganic scintillator has a high cross-section for gamma rays. Because of their different decay times, the pulses of the two scintillators have a different pulse shape. Hence, they can be separated by applying pulse shape analysis \cite[]{Scharrenberg-etal-2013}.
\item[\ac{RETA}] on \ac{BEXUS}-13. In order to investigate the radiation environment in the atmosphere a particle telescope consisting of four segmented silicon semiconductor detectors was developed. Due to the arrangement of the detectors, it is possible to separate neutral and charged particles and the calculated dose rates can be converted into a dose equivalent rate which is the unit for radiation protection. The \ac{FRED} has successfully made such measurements onboard a stratospheric balloon \cite[]{Moeller-etal-2011}. \item[\ac{RETA}] on \ac{BEXUS}-13.
