The ICARUS detector is the world’s first large liquid-argon neutrino hunter. It measures 65 feet long and weighs 760 tons. It began its life in Italy, seeking out elusive particles using pioneering technology, and for the past two years underwent upgrades at CERN, the European particle physics laboratory (and home of the Large Hadron Collider).
ICARUS is the largest of three experiments at Fermilab looking for a new kind of neutrino. To get here, it first had to journey thousands of miles over land and sea. The detector was divided in two and traveled on two separate trucks to Basel in Switzerland, where it took a barge to Antwerp, Belgium. There it boarded a ship to the United States, traveling across the Atlantic Ocean and through the Great Lakes to Burns Harbor, Indiana, where it again took two separate trucks to Fermilab in Batavia, Illinois. It safely arrived at Fermilab on July 26, 2017, and it moved into the Fermilab detector hall on Aug. 16, 2018.
ICARUS will be instrumental in answering the question of so-called “sterile” neutrinos and that answer could rewrite our very picture of the universe. Its exciting new journey begins here.
