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 1.8x10{sup 10} electrons is compressed to 20 {mu}m longitudinally and focused to a transverse spot size of 10 {mu}m at the entrance of a 10 cm long column of lithium vapor with density 2.8x10{sup 17} atoms/cm{sup 3}. 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.
