Abstract

Ion orbits in the quadrupole field were calculated for four stability zones using a matrix method. The orbits were compared with those from the approximate formulae previously obtained. The dependence of maximum ion amplitude on initial phase angle was also calculated for x and y directions for respective zones. It has been found that a condition of the second stability zone at the upper tip is useful in obtaining a high resolution peak.
