The extreme fields generated when a high-intensity laser or relativistic electron passes through a plasma offer the potential to accelerate particles over shorter distances than is possible with conventional accelerators. A new study suggests that driving a plasma with protons rather than electrons could be the key to generating TeV electron beams by this process. 
Plasma wakefield excitation with a 24 GeV proton beam
Proton driven plasma wakefield acceleration has recently been proposed as a means of generating high energy electron beams. In this paper, different options for a demonstration experiment with the
