Single-laser scheme for reaching strong field QED regime via direct laser acceleration
Robert Babjak, Marija Vranic
We investigate a single-laser scheme for reaching the strong-field QED regime based on direct laser acceleration (DLA) of electrons followed by their head-on collision with the sam…
Betatron radiation emitted during the direct laser acceleration of electrons in underdense plasmas
Robert Babjak, Marija Vranic
Relativistic laser pulses can accelerate electrons up to energies of several GeV during the interaction with gaseous targets through the direct laser acceleration (DLA) mechanism.…
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…
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…
