Using the "real" 4K USB camera rather than my smartphone gets a better image of the electron beam hitting the screen.  #physics #accelerators

I should have posted an actual 4K image not the 1080p scaled one, but my computer can only process uncompressed 4K at about 5fps, so I was using 1080p for viewing it continuously.
