Principle of Alternating Gradient Acceleration

摘要

Principle of alternating gradient acceleration is proposed to overcome one of the major limitations on laser acceleration: phase slippage due to the difference between phase velocity of acceleration wave and longitudinal speed of accelerated particle. According to the principle, net acceleration can be achieved in various ways even under continuous phase slippage. Single particle dynamics of both longitudinal and transverse motions are investigated under alternating gradient acceleration.
