[Halld-tracking-hw] Grounding & Cabling

[Fernando J. Barbosa]

Hi Gerard,

Yes, there are two pins on the HVB edge connector for GND, these will be 
connected together with the GND wire (insulated, black PVC, solid AWG18, 
copper) and attached to the endplate socket. The wire diameter is 
similar to the straw cables so that the sealing and mechanicals are the 
same.

Best regards,
Fernando



Best regards,
Fernando
