Description
Laser wakefield acceleration is considered a promising and efficient method for increasing electron bunches energy. Despite advantages in acceleration gradients (accelerating field amplitudes up to 1 TV/m), the issue of dephasing between the electron bunch and the accelerating field, caused by the bunch energy gain, remains a complex task. The use of a conical plasma channel leads to an increase in bunch energy due to laser guiding and compression within the channel.
This study demonstrates that increasing the laser pulse power enhances the electron bunch energy but significantly alters the wake bubble shape. This is results in the absorption of the electron bunch by the rear wall of the wake bubble, as well as leads to dephasing between the bunch and the accelerating field.
Using numerical simulations, the dependencies of bunch parameters, including energy and dimensions, on laser power were obtained. It was shown that found optimal laser power values provided a balance between avoiding bunch absorption and maximizing energy gain.
