We present the design of a Scanning Tunneling Microscope (STM) for measurements at variable temperatures from 300K down to 4K. The microscope will be placed in a 4He cryogenic system with a superconducting coil. This will allow measurements in cryogenic vacuum and optionally in static magnetic fields up to 17 Tesla. The STM is equipped with a sample cleaving mechanism to prepare samples in vacuum and at low temperatures.
