Mr. SQUID® is a complete Superconducting QUantum Interference Device (SQUID) system based on high-temperature superconductor (HTS) technology. The Mr. SQUID® system consists of an HTS thin-film SQUID chip mounted on a rugged probe with removable magnetic shield, a battery-operated electronics control box, and a vacuum dewar flask. The Mr. SQUID® probe is immersed in a liquid nitrogen bath in the vacuum dewar flask, and the electronics control box is used to display the SQUID characteristics on an oscilloscope or x-y chart recorder.  An extensive 100-page User’s Guide is provided detailing the operation of Mr. SQUID® and includes many experiments suitable for laboratory experiment courses. Mr. SQUID® demonstrates the principles of superconductive electronics with the addition of only liquid nitrogen and either an oscilloscope or an x-y chart recorder.
