It survived a month-long journey over 3,200 miles, and now the delicate and complex electromagnet is well on its way to exploring the unknown. The Muon g-2 ring has successfully cooled down to operating temperature and powered up, proving that even after a decade of inactivity, it remains a vital and viable scientific instrument.
You are looking at a silicon detector at the end of the inflector region of the Muon g-2 experiment. This region is the area in which a specialized magnet bends muons after they exit the Muon Delivery Ring (the former Antiproton Debuncher) and enter the Muon g-2 storage ring, which curves to the left in the picture.
One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the U.S. Department of Energy’s Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from Long Island, New York. This week, the magnet took the final few steps of that journey, moving across the Fermilab site and into the new building that now houses it.
