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

Figure 5

The distribution of the composite magnetic field intensity along the axial direction with different radial sizes of the permanent magnet based on the model shown in Figure 3(a). The radii of the permanent magnet are 32 mm, 37 mm, and 42 mm, respectively; the magnetic field strength of solenoid coil is 1 T; and that of permanent magnet is 1.4 T.
