Improved Bethe-Heitler positron creation and retention by combining direct laser acceleration and solid target interaction within a gas jet
Lucas I. Iñigo Gamiz, Robert Babjak, Bertrand Martinez +1
The next generation of Petawatt-class lasers presents the opportunity to study positron production and acceleration experimentally, in an all-optical setting. Several configuration…
Direct laser acceleration in varying plasma density profiles
Robert Babjak, Bertrand Martinez, Miroslav Krus +1
Direct laser acceleration has proven to be an efficient source of high-charge electron bunches and high brilliance X-rays. However, an analytical description of the acceleration in…
Direct Laser Acceleration of Bethe-Heitler positrons in laser-channel interactions
Bertrand Martinez, Robert Babjak, Marija Vranic
Positron creation and acceleration is one of the major challenges for constructing future lepton colliders. On the one hand, conventional technology can provide a solution, but at…
The Influence of Laser Focusing Conditions on the Direct Laser Acceleration of Electrons
H. Tang, K. Tangtartharakul, R. Babjak +12
Direct Laser Acceleration (DLA) of electrons during a high-energy, picosecond laser interaction with an underdense plasma has been demonstrated to be substantially enhanced by cont…
Direct laser acceleration: A model for the electron injection from the walls of a cylindrical guiding structure
P. Valenta, D. Maslarova, R. Babjak +3
We use analytical methods and particle-in-cell simulation to investigate the origin of electrons accelerated by the process of direct laser acceleration driven by high-power laser…
