A METHOD FOR MAINTAINING THE ACCELERATION RATE AND INCREASING THE ENERGY OF SELF-INJECTED BUNCH DUE TO THE USE OF INHOMOGENEOUS PLASMA

Abstract

The paper considers the process of excitation of a wakefield in a plasma by a laser pulse. The plasma density corresponds to the density of free electrons in the metal. A method is demonstrated for keeping self-injected bunch in the accelerating phase of the wakefield as laser pulse and bunch move in plasma with an increasing density gradient. Thus, the rate of acceleration of self-injected bunch is maintained and enhanced.
