It was likely the biggest Family Open House ever at Fermilab. With an estimated 3,700 attendees, the Feb. 12 event attracted enough people to fill the atrium, One West and Ramsey Auditorium.
The annual event featured tours of both Remote Operation Centers, the Fermilab Art Gallery, the Linac and the Main Control Room, as well as driving tours around the Fermilab site. Also featured were screenings of short films in the 15th-floor theater and the always popular Mr. Freeze’s Cryogenic Show. A new demonstration, Dynamic Forces, took place in One West, and attendees even got to take a virtual tour of the Sanford Underground Research Facility in South Dakota, home of the future DUNE far detector.
The atrium provided plenty of opportunities to learn physics concepts, with science demonstrations about magnetism, gravity and electricity.
The event was made possible by an anonymous donor to the nonprofit organization Fermilab Friends for Science Education.
