Proton Accerelation
Utilizing plasma processes to generate high energy protons
Proton Acceleration
Proton and ion beams are highly desired for their applications in medicine and experimental physics. Unfortunately, such beams seldom reach the charge or energies of electron beams due to the particles' mass. Our group explores numerous techniques to achieve high charge, MeV proton and ion beams. Such techniques include TNSA acceleration in foil targets, where the charge separation produced by a laser in a target causes high energy electrons to pull ion bunches through the rear of a plasmized, thin solid. We seek to push the limits of energy and charge in proton bunches by exploring higher energy interactions and unique target geometries.
