Feedthrough Panel
Provide a physically realistic hermetic panel entry or thermalization flange interface for cryogenic RF and DC signal paths.
What it does
Hermetic feedthrough panel assembly providing a room-temperature signal entry or cold-stage thermalization interface. A rectangular mounting plate carries one SMA bulkhead connector through a sealed penetration, with a below-plate hermetic shoulder and above-plate hex coupling nut for cable mating.
Where it goes
- Allowed stages
- 300K, 50K, 4K, Still, CP, MXC, 1K
- Preferred stages
- 300K
- Typical line types
- xy, readoutIn, readoutOut, flux, dc
- At 300 K, represents a hermetic feedthrough panel entry (Bluefors RF installation set style).
- At cold stages, represents a thermalization flange feedthrough.
