Type of article: Article

Summary

A LIQUID HELIUM CRYOSTAT IS DESCRIBED FOR USE WITH THE SCANNING ELECTRON MICROSCOPE (SEM) CAMSCAN 4-DV. THE BACK OF THE SAMPLE IS IN DIRECT CONTACT WITH THE LIQUID HELIUM WHILE ITS FRONT CAN BE IRRADIATED WITH MICROWAVES AND WITH THE ELECTRON BEAM OF THE SEM. THE MICROWAVE SOURCE, EG A KLYSTRON, AND THE OTHER MICROWAVE COMPONENTS ARE ARRANGED OUTSIDE THE CRYOSTAT AND CAN EASILY BE CHANGED DURING OPERATION OF THE SYSTEM. THE MICROWAVE IS THEN GUIDED BY A WAVEGUIDE TO THE VICINITY OF THE SAMPLE. THE SYSTEM IS WELL SUITED FOR SPATIALLY RESOLVED IMAGING OF LOW TEMPERATURE PROPERTIES OF MICROWAVE IRRADIATED SAMPLES.
