Ultrashort Laser Wakefield Acceleration (LWFA) enable the development of new coherent electron and X-ray sources and are implemented in the femtosecond material diagnostics, biomedical research and ionising radiation therapy. The development of stable, high-brightness compact laser sources of ionising radiation requires the matching of the LWFA laser beam parameters and the characteristics of plasma channel. Adaptive free-shape form of parabolic mirror allows to control the spatial-temporal coupling of laser pulse and generate quasi-non-diffracting beam with tailored pulse velocity in the gas jet. It will result in longer acceleration distance, more stable accelerated charge required for generation of coherent X-ray radiation. As for now, only few papers are published on the results of generation of quasi non-diffracting beams and formation of plasma channels using adaptive free-shape parabolic mirrors. According to our knowlege, there are no papers published on the LWFA acceleration of charged particles using quasi non-diffracting beams with with tailored pulse velocity in the plasma.
