Abstract
Based on a set of nonlinear coupling equations describing the interaction of the HF field, self-generated magnetic field, and ion-acoustic wave, the dispersion relation of hybrid transverse plasmon under the circular self-generated magnetic field is obtained. The analysis of magnetic modulation instability shows that the circular self-generated magnetic fields have the tendency to self-similar collapse which makes the electron escape along the axial region and form a collimated jet. In addition, the velocity of the electron jets is calculated, and the result is consistent with experimental observation. The present research may be applied to understand the dynamic process of electron jets produced in laser plasma.
