\chapter{Module Assembly}

\section{Chapter 2}
$\bullet$ Make sure that you have all components on the check list (see Appendix B).
\\
$\bullet$ Make sure you are wearing gloves.
\\
$\bullet$ Make sure that all components are clean.
\\
$\bullet$ Check integrity of all O-rings.
\\
$\bullet$ Introduce beam-pipe O-ring into baseplate cavity.
\\
$\bullet$ Place the blanking plug into the central cavity (for outer modules only).
\\
$\bullet$ Install the ten sixteen pin glass feedthroughs, making sure that each has an O-ring.
\\
$\bullet$ Install the `gas in' and `gas out' SwageloK fitting (ensuring that each has an O-ring).
\\
$\bullet$ Install twelve vacuum feedthrough conhex connectors.
\\
$\bullet$ Install the four baseplate legs.
\\
$\bullet$ Install the baseplate O-ring (ensuring it's integrity before doing so).
\\
$\bullet$ \em Gently \rm install the three baseplate PCB's.
\\
$\bullet$ Attach the three bundles of coloured gas signal wires to the 3 pin (male) connectors on the baseplate PCB's.
\\
$\bullet$ Check the continuity of these wires from the gold connector (at the head of the wire) to the feedthroughs at the back of the baseplate.
\\
$\bullet$ Attach the gas anode bias lead to the conhex connector nearest the `gas in' socket. And check its continuity.
\\
$\bullet$ Leak check the baseplate after it's assembly is completed.

\section{Chapter 3}

$\bullet$ Screw four legs (A2-32/8052) onto the CsI scintillator mount (A0-32/8045).
\\
$\bullet$ Attach four 60mm threaded rods to the CsI scintillator mount.
\\
$\bullet$ Make sure all CsI scintillators have an insulating ring, and a pre-amplifier board attached.
\\
$\bullet$ Place the CsI scintillators into mount, making sure that the load of each scintillator is taken by the two springs.
\\
$\bullet$ Screw CsI scintillator clamp into place (A0-32/8046).
\\
$\bullet$ Attach CsI scintillator ribbon cable. And check the continuity of each line on the ribbon cable.
\\
$\bullet$ Screw the scintillators and mount onto the baseplate.

\section{Chapter 4}

$\bullet$ Place four 4mm insulators onto the four threaded rods, which are attached to the CsI scintillator mount.
\\
$\bullet$ Place PSD PCB onto the four threaded rods.
\\
$\bullet$ Push the three fifteen line ribbon cables onto the three vertical fifteen pin (male) connectors which are fixed to the baseplate PCB's.
\\
$\bullet$ Check the continuity between the PSD PCB and the feedthroughs at the back of the baseplate.
\\
$\bullet$ Carefully place the PSD's onto the PSD PCB. Making sure that the middle energy pin on the PSD is attached to the middle connector on the PCB, which has a soldered track.
\\
$\bullet$ Place four 6mm insulators onto the four threaded rods, which are attached to the CsI scintillator mount.
\\
$\bullet$ Place the cathode grid onto the four 6mm insulators. Attach the earthing lead to one of the CsI mount legs.
\\
$\bullet$ Place four 24mm insulators onto the four threaded rods, which are attached to the CsI scintillator mount.
\\
$\bullet$ Place the anode grid onto the four 24mm insulators. 
\\
$\bullet$ Screw four nuts onto the four 60mm threaded rods. This secures the grids and PSD PCB in place.
\\
$\bullet$ Connect the gas bias lead to the connector on the anode grid
\\
$\bullet$ Connect the coloured wires from the three pin connector on the baseplate PCB to the anode grid.
\\
$\bullet$ Check the continuity of the signals from the anode grid to the back of the baseplate.
\\
$\bullet$ Place module vessel O-ring into the groove at the top of the vessel (ensuring it's integrity before doing so).
\\
$\bullet$ Bolt the blanking plate to the top of the module vessel using M4 16mm (vacuum relieved) screws.
\\
$\bullet$ Lower the module vessel onto the baseplate, and secure in place using M4 23mm (non-modified) screws.

\section{Chapter 5}
$\bullet$ Screw the 174mm and 187mm threaded screw rods into the back of the baseplate.
\\
$\bullet$ Lower the three pre-amplifier cans onto these rods. Making sure that the three black female connectors at the bottom of each can seat correctly onto the glass feedthroughs.
\\
$\bullet$ Attach the handles to the outer 187mm threaded rods. And fix the pre-amplifier cans down with nuts and washers.

\section{Chapter 6}

$\bullet$ Remove blanking plate from module vessel.
\\
$\bullet$ Replace with mylar window and window clamp.
\\
$\bullet$ Screw calibration grid onto window clamp.
