First vertex detector

The Positron Electron Project (PEP) collider at the Stanford Linear Accelerator Center produced its first collisions in 1979. All sorts of particles burst out, including the tau lepton, an ephemeral cousin of the electron.

A top gradient for cleanliness

After undergoing a buffered chemical polishing (BCP) treatment at Cornell University, the first US-processed and tested International Linear Collider superconducting cavity achieved a milestone accelerating gradient of 26 MV/m (megavolts per meter)–surpassing the first gradient goal (25 MV/m).

Particle physics takes flight

Welcome to SLAC's End Station B, where work on the International Linear Collider (ILC) will help shape the future of particle physics–although some inhabitants don't seem to give a hoot.

Ellis Paul: Did Galileo pray?

The sighting of Jupiter's moons by Galileo Galilei resonates through science and history. Using a handmade telescope in January 1610, Galileo confirmed the Copernican theory that the planets moved around the sun; the Earth was not the center of the solar system.
