Radially polarized (RP) Hermite-Cosh-Gaussian (HChG) laser beam has been employed to study electron acceleration in an ion channel. As RP-HChG laser beam focus earlier, depending on this property electron acquires high order energy over short periods of time. The ion channel generates an electric field that prevents electrons from escaping from the interaction zone and maintains betatron resonance. Electron’s energy gain has been analyzed by varying different parameters like: intensity parameter (
), laser spot size (
), decentered parameter (
), ion density (
). The combined effect of RP-HChG laser beam and ion channel causes an efficient energy enhancement of electron in the order of GeV. RP-HChG beam is a unique kind of laser beam, combining the characteristics of both Hermite Gaussian and hyperbolic cosine Gaussian modes. It can be tightly focused to produce a small spot with a high-intensity region at the focal point.
