An Axial Foilless Diode Guided by Composite Magnetic Field for the Production of Relativistic Electron Beams

Figure 4

The distribution of composite magnetic field intensity along the axial direction under different arrangements of soft magnetic, as shown in Figure 3. The curves (a), (b), (c), (d), and (e) in this figure correspond to the structure models (a), (b), (c), (d), and (e) in Figure 3, respectively. The magnetic field strength of solenoid coil is 1 T, and that of permanent magnet is 1.4 T.
