Thesis: Exploring the geometry and performance of cryocooler re-condenser designs.

2. Cryocooler Re-condensers
Used to re-condense stored cryogens for
Superconducting electromagnets: Particle accelerator magnets, MRI, motors, generators, etc.
Cryogen storage depots in space
Helium is the working fluid inside the cryocooler, and the condensing fluid outside the cryocooler
Thermal resistance between cryocooler cold tip and the surrounding helium gas causes inefficiency
Cold tip

3. Re-condenser Optimization
Project goals
Minimize thermal resistance
Optimize condensation rate
Geometry and extensions
Determine appropriate geometry to adequately move condensed gas to liquid phase
Investigate influence of surface preparation
Extend condensing surface into the saturated bath?
