Superconducting Devices in Electron Microscopy
The improvements gained by superconducting devices in electron microscopy are due partly to the properties of the superconductors and partly to the low temperatures which must be maintained. However, the low temperatures give rise to the most important disadvantage, namely the necessity for cryogenic techniques.
