| Abstract | ||
| A gcncral approach havc bccn outlincd to calculatc thc frst ordcr propcrtics and thc third Ordcr abcrrations of a chargcd p7articlc passing through a l■ lagnetic rleld The featurc of this procedurc is that it may bc considcrcd on analytical approach and hencc it is absent from thc sorts of crrors usually inhcrcnt with thc numcrical proccdure 「his approach, howcvcr,is bascd as an thc ncw analメiCal mcthod for solving thc wclト known paraxial ray cquation which is introduccd latcr Accordingly, tllc convcntional abcrration and distortion coefacients have been fonnulatcd by uslng thヽncw ldca Thcrcancr,an ottCa市c cOmparisonヽmadc bctwccn the formulated expressions and the correspondence analytical forms' The results have clearly shown that they are exactiy identical. Thereby, the introduced approaih may be used to replace any numerical approach dealing with- the passing of a charge particle throughout any electro=magnetic imaging fields. Moreover, the presented approach is simpler than the conventionai numerical techniques and has less storage size and execution time. | ||
