Physical Review Focus : High-energy physicists have finally pinpointed their dust problem. Inside multi-million dollar storage rings, high-speed trains of electrons are often derailed by micron-sized specks of dust. Now a team has shown that dust grains arise from sparks inside a Japanese storage ring, the KEK Photon Factory Advanced Ring as they report in an upcoming paper in Physical Review Special Topics--Accelerators and Beams.The team also caught on video, one of the tiny grains being swept along in the electron beam. The brief flashes of dust trapped in an invisible electron beam begin about halfway through the 10-second video.
