Cosmic Rays at Fermilab’s NOvA

Cosmic rays are zipping through your body during every nanosecond of every day. This has been going on, right here on planet earth, since the beginning of planet earth. There’s nothing you can do about it. Except, perhaps, watch it happen. Here’s a screen shot of what it might look like. But it changes ever 15 seconds, or so.

The NOνA (NuMI Off-Axis ν_e Appearance) experiment is a particle physics experiment designed to detect neutrinos in Fermilab’s NuMI (Neutrinos at the Main Injector) beam.

This page takes you to the NOvA Far Dectector. (Also to the Near Detector, but we won’t talk about that.) The image refreshes every 15 seconds. The colorful displays are a 500μs (500 microseconds or .0005-second) long window of time, mostly showing long straight tracks from cosmic ray muons: about 40 in any given 500μs time window.

Good information to know. Perhaps you can use it to sue someone, or at least get a refund from whomever decided to spray you with cosmic rays without your written permission.  [Chuck Almdale]
