Liquid-free cryogenic devices are acquiring importance in basic science and engineering. But they can also lead to improvements in teaching low temperature and solid-state physics to graduate students and specialists. Most of the devices are relatively expensive, but small-sized equipment is slowly becoming available. Here, we have designed several simple experiments which can be performed using a small Stirling refrigerator. We discuss the measurement of the critical current and temperature of… Expand

Vibration-free stirling cryocooler for high definition microscopy
The authors have successfully adapted the standard low vibration Stirling cryogenic refrigerator delivering 5 W@40 K heat lift for use in vibration-sensitive high definition microscopy by using passive mechanical counterbalancing of the main portion of the low frequency vibration export in combination with an active feed-forward multi-axes suppression of the residual wideband vibration.
