Method for maximizing the brightness of the bunches in a particle injector by converting a highly spacecharged beam to a relativistic and emittancedominated beam
Abstract
A method for maximizing the brightness of the bunches in a particle injector by converting a highly spacecharged beam to a relativistic and emittancedominated beam. The method includes 1) determining the bunch charge and the initial kinetic energy of the highly spacecharge dominated input beam; 2) applying the bunch charge and initial kinetic energy properties of the highly spacecharge dominated input beam to determine the number of accelerator cavities required to accelerate the bunches to relativistic speed; 3) providing the required number of accelerator cavities; and 4) setting the gradient of the radio frequency (RF) cavities; and 5) operating the phase of the accelerator cavities between 90 and zero degrees of the sinusoid of phase to simultaneously accelerate and bunch the charged particles to maximize brightness, and until the beam is relativistic and emittancedominated.
