Superconducting Quantum Interference Devices are are spectacularly sensitive magnetometers based on Josephson junctions. Applications of SQUIDS vary from "mindreading" to testing General Relativity. In this experiment, basic properties of SQUIDS will be studied and some advanced experiments done. Brian Josephson received the Nobel Prize in 1973 for his prediction of the Josephson effect.
(The experiment is currently located in MP239; last write-up revision: 2004.)
