\title{AHEPaM Assembly procedure}

\begin{document}
\maketitle
This procedures describes the assembly of the AHEPaM DM/FM. \newline
Section 1 gives some clarifications/definitions regarding the naming scheme.\newline
The procedure is split in three parts,
\begin{itemize}
    \item Detector assembly (section 2, 4 weeks total)
    \item Preamp board assembly (section 3, 3 weeks total (1.5 weeks for DM))
    \item final assembly (section 4, 2 weeks total)
\end{itemize}

\section{Clarifications / definitions}
The detector set-up can be seen in fig. \ref{fig:telescope-specs}. This includes the positions and naming scheme of the SSDs (SSD-A till SSD-E). For the Cherenkov detectors and the BGOs, in the following we will name
\begin{itemize}
    \item BGO-1: the BGO in-between SSD-B and SSD-C
    \item BGO-2: the BGO in-between SSD-C and SSD-D
    \item CHKV-1: the Cherenkov in-between SSD-A and SSD-B
    \item CHKV-2: the Cherenkov in-between SSD-D and SSD-E.
\end{itemize}
The E-Box and Board set-up is depicted in fig. \ref{fig:ebox-board-stack}. In the following we will name
\begin{itemize}
    \item base-frame: upper segment of the E-Box. The detectors are mounted on top of the base-plate, the Preamp-Boards are housed in this segment
    \item filter-frame: middle segment of the E-Box. This segment houses the Shaper-/Filter-boards
    \item backend-frame: lower segment of the E-Box. This segment houses the Analog, LVPS, HVPS boards.
    \item Revisionsopening: open segments of filter-frame for Jumper-Harness assemblies
\end{itemize}
