  • Thin-walled cryostat
    Patent number: 5941080
    Abstract: A cryostat includes an upper shell and a lower shell connected along a seam. The shells are made of a relatively thin material which would be subject to collapse once the cryostat is evacuated. In order to resist collapsing forces, a brace is placed inside the cryostat between opposing walls of the shells. The brace has a connecter which includes a pin and post that has an opening for receiving the pin. The connectors allow easy assembly and disassembly of the cryostat while still resisting compressive forces.
