- Abstract:
- The need of a superconducting magnetic shield erases in several physical apparatus, going from the small SQUID sensors to the large superconducting magnets for physical experimentation and clinical MRI. It is presented the possibility to realize cylindrical magnetic shields by HTS bulk MgB2 (Tc=39 K), obtained by the innovative process of Reactive Liquid Infiltration of the Mg melt in Boron powders. A complete shielding up to at least 2 T can be obtained also at the lower temperatures, 4.2 K, where thermal instabilities of the other LTS shields prevent their use.
