The effect of magnetic field generated by the interaction of high-intensity laser pulse and low-density plasma on electron bunch acceleration in the bubble regime

Document Type : Full length research Paper


In this paper, the effect of the magnetic field generated by the interaction of femtosecond high-intensity laser with under-dense plasma in the bubble regime on the acceleration of an electron bunch with Gaussian distribution in velocity and position has been studied. It was seen that the magnetic field could increase the final energy of electron bunch from about 1 GeV to approximately 1.2 GeV and reduces the final energy spread. Also, the final emittance of electron bunch decreased about one order of magnitude and it has been equal to 0.38 * 10^-3 mm mrad. Moreover, we observed that the magnetic field caused ten percent increment in number of accelerated electrons.
