Remote-controlled magnetic horn replacement 200 feet underground

Fermilab uses magnetic focusing horns to create intense neutrino beams for physics experiments. The horns operate in a tough, corrosive environment, exposed to heat, radiation and mechanical stress. They pulse 200,000 amperes of electric current every 1.2 seconds to create extremely powerful magnetic fields. Over years of service, the horns reach their end of life and must be replaced. This four-minute time lapse shows the removal and storage of one of these focusing horns and the installation of its successor. The old horn was installed in 2008 and focused more than 129 million pulses before being replaced in 2020. All the material moves shown in the video were achieved via remote-control cranes and video cameras. So how do scientists produce neutrinos? Fermilab’s particle accelerators send a powerful beam of protons into a graphite target. When the protons strike the target, the interaction creates secondary particles that eventually decay into neutrinos. Two magnetic focusing horns steer the emerging secondary particles into the right direction, prior to their decay into neutrinos.
