Monte Carlo simulation of ion trajectories in the kinematic recoil separator “VASSILISSA”☆

In order to calculate the transmission of ions through the kinematic separator VASSILISSA a Monte Carlo computer code was developed, The program considers the effects from reaction kinematics, momentum transfer from the evaporated particles to the evaporation residues (ER), scattering and energy losses of ER's in the target and foils and the ion charge distribution of ER's, The results of calculations are further combined with the first-order ion optics to simulate the trajectory of each ion. Simulation of the time-of-flight, energy, position, charge distribution spectra for different reaction products is also possible.
