STM Superconducting Magnet System
with Optical Access

August 1999

An 8 T split superconducting magnet system has been designed and built for a Scanning Tunneling Microscope with optical access to the microscope cooling stage.   The microscope is top loaded into a UHV space that can be baked out to a temperature of 150 degrees Celsius without affecting the superconducting magnet or the rest of the cryostat.   The system offers variable temperatures from below superfluid helium temperatures up to room temperature.   Several variations are available on this basic design, enclosing bottom optical access, cryostats for Scanning Near Field Optical Microscopes, Atomic Force Microscopes, etc.   Please contact Janis for more detailed information or for a custom system designed system for your application.
