We report the construction of a compact cryogenic scanning tunneling microscope. The design will allow to study local electronic structures at temperatures down to 2.5 K and magnetic fields of up to 15 T with atomic resolution in real space and a high energy resolution of 2 meV at 6 K. The microscope has a scanning range of 1µm x 1µm and a built-in cleaving mechanism that renders it possible to cleave the samples at a cryogenic temperature. Samples can be exchanged within a day while the measurement time can reach up to 6 weeks. These qualities combined with its compact and portable design make this STM a comfortable tool to study low temperature phenomena, e.g. superconductivity.
