A UHV-STM system for measurements at 300 mK and 14 T — •Stefan Becker, Marcus Liebmann, and Markus Morgenstern — II. Physikalisches Institut B, RWTH Aachen and JARA-FIT, Otto-Blumenthal-Straße, 52074 Aachen

We have designed an ultrahigh vacuum (UHV) system featuring a homebuilt scanning tunnelling microscope (STM) inside of a 300 mK cryostat with a 14 T solenoid magnet exhibiting a single-shot time of 100 h. Two independent chambers hold various instruments for sample and STM tip preparation, including sample heaters, a sputter gun, evaporators and a combined LEED/Auger system. The STM body is compact and rigid (Ø 30 mm) for stability and high resonance frequencies. It has an in situ tip exchange mechanism and a sample positioning stage. The whole system is supported by air damping legs inside an acoustically insulating room.
