Design and first results of a ultra low temperature scanning tunnelling microscope — •Danny Baumann¹, Martha Scheffler¹, Ronny Schlegel¹, Torben Haenke¹, Christian Hess¹, Marko Kaiser², Ralph Voigtländer², Dirk Lindackers², and Bernd Büchner¹ — ¹Institut für Festkörperforschung, IFW Dresden — ²Bereich Forschungstechnik, IFW Dresden

We present the design of a home build 300 mK, ultra high vacuum (UHV) scanning tunneling microscope (STM). The STM is equipped with a 9 T superconducting magnet, a home build xy-sample positioning system, in situ tip and sample exchange, radio frequency filter for all relevant signals as well as a three chamber UHV system to prepare, analyze and store tips and samples.

Furthermore, we show the results of energy calibration measurements with different tip-sample configurations using a Niobium BCS superconductor.
