摘要：

Ion optics of multiturn time-of-flight mass spectrometer that satisfy both perfect space and time focusing were investigated. The basic concepts of perfect focusing are explained. It was found that the perfect focusing conditions can be reduced by introducing symmetrical geometries. The conditions are expressed in the transfer matrix form. (C) 2000 Elsevier Science B.V.
