Are there assembly drawings and manufacturer parts lists available for all the individual cable & board assemblies for the detector? We would like to see these for a deeper understanding of the system, in particular,  how the voltage connections are made from the patch panel to the PMTs, e.g. what kind of cables are used inside to make the connections.
