Search for Magnetic Monopoles
For the past three years we have been cooperating with researchers under the external page MoEDAL (Monopole and Exotic Detector at the LHC – Large Hadron Collider) project at external page CERN in their search for magnetic monopoles. One type of detector consists of aluminum rods that were exposed 13TeV proton-proton collisions near the external page LHCb interaction point. The presence of a monopole would cause a trapped flux, i.e., persistent current, in the SQUID sensors. Over 800 kg of samples have been passed through our long-core cryogenic magnetometer to search for trapped flux in SQUIDS. No magnetic monopoles have been discovered until present, but the serach continues.
