The performance of the cable assemblies are certified via helium leak
testing by an independent test laboratory. Window and stub assemblies
are not certified.
Maximum helium leak rates
of 10-11 cm3/sec (torr) are achievable with single fibre cables and
10-9 cm3/sec (torr) with bundled fibres. Operating temperature range
is -40°C through +100°C.
The vacuum seals are
2.16" diameter aluminum NW40 flanges or .375" O.D.
