Caption: Dr Blas Cabrera poses beside his magnetic monopole detector in the basement of the physics department at Stanford University, California. The detector's core is three loops of superconducting wire which register any magnetic charge, which is then monitored by three SQUIDs (Superconducting Quantum Interference Devices) which are in the grey boxes evenly spaced around the detector. Magnetic monop- oles are important for Grand Unified Theories in physics, for Big Bang theory & for the hidden mass problem in cosmology. Cabrera built the first magnetic monopole detector in 1981 & obtained a single magnetic monopole candidate. The detector shown here stated operating in 1983.
