The gyration orbit of a relativistic electron in the x - z plane, based on Eqs. (20) and (21). The initial velocity \( \widehat{z}\ {z}_0=-\widehat{z}\ 0.31\times {10}^8 \) m/s at (t = 0), E (t) = \( -\widehat{z}\ 400\ cos\omega t \), B = 2.0 T, \( {\omega}_c=\left|\widehat{y}\kern0.50em 3.5\times {10}^{11}\right| \) sec⁻¹ and the flight time t = 0~(2π/ω_c) n =3 × 10⁻⁸ sec when n = 1670. This figure is related with Fig. 8c
