The MHV cables in the assemblies listed below consist of Accu-Glass Products' TYP6, 26 AWG, 50-Ohm coaxial cable. These components are rated to 250°C and 1 x 10-10 Torr.
Connector to Cable in-vacuum UHV cable assemblies are fitted with stainless steel Accu-Fast™ or MHV male bayonet connectors at one end and a "Connector #2" selectable option on the other. Connector #2 options: MHV male, User-End female, or non-terminated.
The connectors mate directly to the in-vacuum side of MHV feedthrough flanges.
MHV Coaxial Interface
The 'Miniature High Voltage' connector interface is designed for low noise 50-ohm lines requiring higher voltage than is possible with a standard BNC interface. MHV coaxial feedthroughs are constructed in both grounded and floating shield configurations. Floating shield types provide two concentric conductor paths: an outer metal conductor tube (shield) concentric with, and enclosing, a cylindrical center conductor pin. Both paths are electrically isolated from each other and a mounting flange. Grounded shield MHVs provide only one path that's electrically isolated from the flange; where grounded shield and flange are electrically common. Vacuum side of single-ended grounded and floating MHV feedthroughs have a 0.094 inch (2.4-mm) diameter conductor pin that mates with grounded or floating AccuFast™ connectors.
