Intense Laser Acceleration of Quasi - Monoenergetic Protons

Title of Document: INTENSE LASER ACCELERATION OF QUASI-MONOENERGETIC PROTONS Tung-Chang Liu, Doctor of Philosophy, 2013 Directed By: Professor Chuan S Liu, Physics By irradiating an ultra-thin overdense foil with an intense circularly polarized laser beam, the laser radiation pressure can push the foil forward. This scheme, laser radiation pressure acceleration, is one of the most actively stud...

Laser-wakefield acceleration of monoenergetic electron beams in the first plasma-wave period.

Beam profile measurements of laser-wakefield accelerated electron bunches reveal that in the monoenergetic regime the electrons are injected and accelerated at the back of the first period of the plasma wave. With pulse durations ctau >or= lambda(p), we observe an elliptical beam profile with the axis of the ellipse parallel to the axis of the laser polarization. This increase in divergence in ...

Parametric amplification of laser-driven electron acceleration in underdense plasma.

A new mechanism is reported that increases electron energy gain from a laser beam of ultrarelativistic intensity in underdense plasma. The increase occurs when the laser produces an ion channel that confines accelerated electrons. The frequency of electron oscillations across the channel is strongly modulated by the laser beam, which causes parametric amplification of the oscillations and enhan...
