The beam in a laser wakefield can be slowed down by laser-induced, large-amplitude betatron oscillation, leading to potential larger dephasing length between the beam and the wake field and in turn a higher beam energy.
Electron and proton trapping and acceleration by an electron bubble in laser interaction with plasma are investigated by using three-dimensional particle-in-cell simulations. A nanowire is used to initialize the wave-breaking. Protons can be efficiently accelerated if the plasma consists mainly of heavier ions such as tritium.
