| Abstract | The widening use of the “dry-cooling” technology, that is replacing the traditional use of present liquid nitrogen facilities in high-resolution and the inherently need for vibration sensitive instrumentation, such as Scanning Electronic Microscopes, Helium Ion Microscopes, Superconductive Quantum Interference Devices, etc. have motivated further R&D activity towards developing vibration-free closed cycle mechanical refrigerators. The authors successfully adapted the low vibration standard of the Ricor model K535-LV Stirling cryogenic refrigerator for use in vibration-sensitive nano-resolution electronic microscopy. The objective has been achieved by preliminary passive mechanical counterbalancing of a large portion of the low frequency vibration export followed by an active feed-forward multi-axis control of residual wideband vibration. The attainable performance of the ultra-low vibration linear Stirling cryogenic refrigerator of the Ricor model K535-ULV was evaluated through the full-scale experimentation. |
