You mean one of these Terry
This LS-band (~2GHz) receivers' cold finger in this unit is immersed in a nice cool 14-18 degK bath. It's all so critical that they hire a bloke just to maintain it and several others. He's our mate John - the cryogenics engineer at ATNF Narrabri. He's the one on the left. The other is Jenny, my wife. Confusing them earns me a slap across the chops.
