The Livingston chart depicts the development of these devices. A detector called a pickup and a corrective “kicker” are used in a feedback mechanism in these devices called stochastic cooling. The Bjorken-Mtingwa model describes a form of scattering in these devices that causes phase space volume to increase, increasing the emittance. In 1974, a simultaneous event at two of these devices (15[1])3000 miles apart was termed the (*) “November Revolution.” Ernest Lawrence invented a resonant type of these devices with two D-shaped chambers, which uses magnetic fields oscillating with frequency “qB over m.” Examples of these devices that bend trajectories into circular shapes emit synchrotron radiation. For 10 points, SLAC and the Large Hadron Collider are what devices that propel charged beams of particles? ■END■
