After the recent discovery of the superconductivity in MgB2, a lot of work has been done to introduce MgB2 conductors in MRI magnets. The main advantages would be relative low costs and working temperatures between LTC and HTC typical values. Ansaldo Superconduttori is developing a cryogen-free open MRI magnet based on a new developed MgB2 superconductor. We will report on the main features of the magnet design and the most significant results obtained during MgB2 tape and demo coil tests. All collected data confirm our preliminary design assumptions, and we are currently completing the prototype magnet.
