For the optimization of the transmission of recoil separators a Monte-Carlo
computer code was developed. A special subroutine generates a set of "real
" particles, which will be stored dynamically in the computer's memory. The
mean program varies the parameters of the focusing system of the separator
in steps, calculates the transmission for each parameter set by transporti
ng a large number of "particles" using the first-order ion optics and searc
hes the best combination of the variables over the permitted ranges of valu
