As I reported in this week’s issue, the Tevatron, the giant particle accelerator run by west-suburban Fermi National Accelerator Laboratory, goes offline today. It’s the end of an era for Fermilab, which now shifts its focus to other types of physics, including the study of tiny elementary particles called neutrinos.

On its website, Fermi is hosting a live video stream of the proceedings: a ceremony starting at 2 PM includes remarks from Fermi director Pier Oddone, after which representatives from the two detectors attached to the Tevatron initiate the shutdown process. The whole thing is expected to last about 30 minutes, with the stream going live at 1:45. Watch it here.
