Investigation of Electron Acceleration using Chirped Radially Polarized Pulsed Bessel-X Beams

Acceleration of charged particles using vector pulsed laser beams is a field that has been gaining interest in recent years. Due to high laser power demand on acceleration it is important to increase the efficiency of such system. The efficiency can be improved by fine tuning the initial phase and beam waist of the laser pulse as has been shown in previous studies [1] . It has been shown that by optimising the initial pulse phase and beam waist it is theoretically possible to reach higher energies (up to 50 MeV with laser power equal to 100 TW) as compared to a non-optimised parameter pair.
