Operation Terminology

Debuncher, Pbar

A radio frequency cavity phased so particles at the leading edge of a bunch of beam particles (higher momentum particles) are decelerated while the trailing particles are accelerated, thereby reducing the range of momenta in the beam. Such a device may be placed between two stages of acceleration to increase the efficiency of capturing the beam.
