Abstract

A plasma-wakefield accelerator has accelerated particles by over 2.7 GeV in a 10 cm long plasma module. A 28.5 GeV electron beam with 1.8×1010 electrons is compressed to 20μm longitudinally and focused to a transverse spot size of 10μm at the entrance of a 10 cm long column of lithium vapor with density 2.8×1017atoms/cm3. The electron bunch fully ionizes the lithium vapor to create a plasma and then expels the plasma electrons. These electrons return one-half plasma period later driving a large amplitude plasma wake that in turn accelerates particles in the back of the bunch by more than 2.7 GeV.
