IFEL electron acceleration due to two laser pulses incident at an oblique angle

The vacuum laser acceleration scheme IFEL has been investigated. We have studied the best conditions for achieving higher energy gain using two laser pulses crossing at an angle in the presence of an undulator. A group of optimized variables for electrons and the laser pulse are employed to numerically investigate the phenomena of the crossing of two lasers using the inverse free electron acceleration (IFELA) mechanism. IFELA mechanism is used to produce a high quality, micro-bunched accelerated electron beam that is used to feed a Compton scattering interaction point, which produce x-rays of directional narrow bandwidth. The effect of linear frequency chirp has been investigated and shown that the final electron energy in the presence of an undulator is strongly dependent on different parameters like the laser’s initial intensity, the crossing angle between the lasers, wiggler magnetic field strength, and the chirping of the laser pulse. It shows that the crossing of lasers plays a crucial role in the final energy gain as compared to the co-propagating lasers. The proportionality of the final energy gain on pre-accelerated electron’s energy is also investigated. Hundreds of MeV energy gain has been obtained in the investigation. Currently these types of lasers are used in scientific research in the field of material science, Chemical engineering, medical science, biophysics, surface studies and solid state physics etc.
