A system and a method for recovery and recycling of gases which are utilized in their liquid state as refrigerants in applications that require low temperatures, throughout various pressure ranges, from slightly above atmospheric pressures to pressures near the critical point for the particular gas. The system and method are based on closed-cycle cryocoolers and utilize the thermodynamic properties of the gas to achieve optimal liquefaction rates.

Superconducting bearings inhibit the excitation of modes in a superconducting force measuring instrument such as a superconducting gravimeter, and effecively damp such modes in the event they are excited. Excitation of modes is inhibited by magnetically and/or physically blocking orbital and rotational motions. Modes which are excited are efficiently damped, preferably by inducing eddy currents in lossy metal parts. These dissipative eddy currents remove energy from the motion, causing the motion to decay exponentially with time. A significant advantage of the bearing design is that the magnetic field of the bearing can be isolated from the main levitation system. This ensures that the bearing interferes minimally with the gravity measurement.
