摘要：

This paper describes a new type of multipassage mass spectrometer using tricylindrical mirrors as reflexive elements and a symmetric quadrupolar lens triplet as focusing element. We study the first order optics and then emphasize on beam transport problems as well as on conditions for maximum mass resolution. The effect of first and second order aberrations on the ultimate resolution of the spectrometer and the procedure for minimizing them by selecting proper operating conditions are discussed. The contributions of the third order aberration terms and of space charge are not considered. © 1990.
