An optimizer for high-current beamlines

A novel approach to the problem of beamline development for high-current electron beam is put forward. A transient electron beam is considered as a set of independent stationary beams with different currents, energies, and initial conditions. In such a way, the overall acceptance of a beamline can be maximized effectively for some conditions and the loss can be predicted well. The simulation code implemented in this approach is described. Some examples of existing and designed beamlines are presented.
