The program is dedicated to numerical simulation of the behavior of highly-charged ion beam and optimization of beam optics in transport lines and is realized on a PC with Windows user interface of Microsoft Visual Basic. Among all the ions with different charge states in the beam, the exchanges of electrons between highly charged ions and low charged ions or neutral,atoms of residual gas are taken into account by using classical Molecular Over-barrier Model and Monte Carlo method. An advanced Windows graphical interface makes it; comfortable and friendly for the user to operate in an interactive mode. The present program is used for the numerical calculation and optimization of beam optics in a transport line consisting of various magnetic elements, such as dipole magnet, quadrupole and so on. It is possible to simultaneously simulate 200,000 particles, in a transport line of 340 m at most, and show every particle orbit. Beam cross section graphics and emittance phase pictures can be also shown at any position in the transport line.展开更多
