Manipulating the Laser-Driven Proton Bunch with Plasma Wakefield
Figure 7
The electric and magnetic field (Ex, Ey, and Bz) in the wakefield region induced by the proton bunch traveling through the plasmas and propagation distance s = 21.6 cm. The blue ellipse in the figure represents the bunch. (a) Longitudinal electric field distribution in plasma (unit is MV/m), (b) transverse electric field distribution in plasma (unit is MV/m), and (c) magnetic field in the direction which perpendicular to the propagation plane (unit is mT).
