Abstract ITAP is a 2 1 2 -dimensional FORTRAN code developed for the first-order design of charged-particle transport systems. The Ion Trajectory Analysis Program (ITAP) utilizes the paraxial-ray equation with no space charge to determine image size and divergence along the beam line. A discretized transfer-matrix technique is used to model particle transport through drift spaces, symmetrical electrostatic lenses, quadrupoles, wein filters, sector mass separators, deflection plates... Title of program: ITAP Catalogue Id: ABTZ_v1_0 Nature of problem The first approach in the design of any beam transport system is the preliminary modelling of the ion-optics to select and optimize the focal properties of the beamline components. Charged particle trajectories must be calculated through the system to determine the excitations, thicknesses, and gaps required on the lens to produce a desired image size and divergence from a given set of object conditions. Versions of this program held in the CPC repository in Mendeley Data ABTZ_v1_0; ITAP; 10.1016/0010-4655(91)90059-T This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
