The plasma helps propagation of a high beamcurrent without divergence. After that, this potential fluctuation leads to oscillation of the reflected electron beamcurrent. Meanwhile, the transmitted electron beamcurrent emerges in this case, which is different from the initial state of total reflection. For relativistic beams, a ray-tracing code must also find the distribution of beamcurrent to calculate magnetic forces. By optimizing the extraction diode geometry and reducing the beamcurrent, the spherical aberration was later improved and therefore the beam profile became more uniform. The beamcurrent normally does not appear in photodetachment neutralizer formulas because the ion beam is optically thin. By removing this outside edge, the beamcurrent will be reduced, but the emittance may be reduced more, so that the total brightness increases. The beamcurrent pulse duration and the pulse repetition rate are determined by the pulse duration and repetition rate of the discharge current. Among the distinctive features of the sources are simplicity, high beamcurrent, and efficiency in producing beams. The injected beamcurrent will also be varied to probe the fill factor. Figure 2 shows the ion beamcurrent and g-output from the target as functions of time. Recent modifications in the laser ion source have been implemented to improve the beam stability and raising the output beamcurrent. In this case, the beamcurrent pulse has two sections with different rise rates. These examples are from corpora and from sources on the web.
