    Schematic of the Betatron radiation source[7]
    When a0=20,ne=0.1nc, the formation of plasma bubble, injection of electron beam, resonance of electron beam and laser, development of bubble instability and other processes during the interaction between laser and plasma at different moments
    When a0=20, ne=0.1nc, (a) angular distribution of electrons att = 500 fs, (b) the angular distribution of total photons at t = 1.2 ps, and full-width-at-half-maximum (FWHM) about 6°
