  We report the construction and performance of a low temperature, high field
scanning tunneling microscope (STM) operating down to 350mK and in magnetic
fields up to 9T, with thin film deposition and in-situ cleaving capabilities.
The main focus lies on the simple design of STM head allowing top loading of
the sample and innovative sample holder design that allows us to get
spectroscopic data on superconducting thin films grown in-situ on insulating
substrates. Other design details on sample transport, chamber and vibration
isolation scheme are also described. We demonstrate the capability of our
instrument through the atomic resolution imaging and spectroscopy on NbSe2
single crystal and spectroscopic maps obtained on homogeneously disordered NbN
thin film.
