In this conceptual art, an electron and positron collide, resulting in a B meson (not shown) and an antimatter B-bar meson, which then decays into a D meson and a tau lepton as well as a smaller antineutrino.
View of the BaBar detector (about six meters in diameter) with staff scientist Michael Kelsey analyzing problems during a shutdown of SLAC’s PEP-II electron-positron storage rings.
When stars explode, the supernovas send off shock waves like the one shown in this artist's rendition, which accelerate protons to cosmic-ray energies through a process known as Fermi acceleration.

A close-upof the XL5 klystron. Manufactured by CPI, it was brought to SLAC for testing at a unique facility that can power the tube with 400,000-volt pulses. Building its own test facility would have cost the company at least...
