Abstract : A set of FORTRAN functions and subroutines has been written to facilitate calculations, using matrix techniques, of the first order properties of ionoptical systems for particle accelerators. These functions and subroutines generate matrices for various magnetic elements used in ionoptical systems and also program various matrix manipulations. A subroutine to calculate the strength of magnetic quadrupoles required to achieve prescribed focal conditions is available. Functions used to calculate the maximum excursion of a particle trajectory from the optic axis in a magnetic element, to calculate the waist of a particle beam if the emittance satisfies certain conditions, and to calculate the location of the focal plane for an arbitrary ionoptical arrangement have been written. Programs can be written, using these functions and subroutines, to calculate the properties of particular ionoptical systems. Illustrative coding shows how such programs are written. (Author)
