\chapter{Introduction}
The MEGHA detection system makes use of multi-telescope modules. The five modules can hold up to forty four, three detector telescopes, and are therefore both sophisticated and complex. Special handling and assembly requirements has lead to the necessity of an ``Assembly and Testing Protocol Manual''. The manual, as well as explaining how to build up a module, will also explain how to test it's signal integrity, prior to installation in the MEGHA scattering chamber.
By assembling correctly and testing prior to installation, it is possible to reduce the amount of time required to rectify signal loss and to leak chase.

While using this manual to built up a module, attention must be drawn to the existing ``MEGHA  MANUAL, by Steve Chappell et al.''. This manual is also an excellent source of information. A copy of both manuals are available at the, Department of Nuclear Physics (Australian National University) as well as the Daresbury document server.
Both manuals have a section where notes and corrections may be entered by the person building up a module. Periodically these corrections will be made to the master copy on the Daresbury server, by the author. So please, if you see any mistakes or have something to add, use the notes section.\\

N.B. \em Prior to working with any part of the module, it is important that each component is free from dust and grease. Any dirt attached to the components will be out-gassed, when installed in MEGHA, and hence will put a greater load on the pumps and limit the systems ability to attain high vacuums. 
It is therefore always a good idea to wear surgical gloves while handling MEGHA. This reduces the risk of the person assembling the module from transferring grease from their hands to the equipment. Any dirty components can be cleaned with dust free tissue paper and an alcohol based solvent. The modules are regularly ultrasonically cleaned, which does removes a large amount of grease.
