β¦ Synopsis
A simple cryogenic stage (liquid nitrogen cooled) is described for use with a Jeol scanning electron microscope. The installation of the stage within the SEM does not require any modification. The stage is capable of achieving temperatures between 80 and 85 K. Movement of the stage required for scanning and otherwise can be obtained with the original micrometer screws.
