Abstract
A computer program TRIUMF for the solution of beam transport problems is described. This program tracks, to first order, particle trajectories and phase space ellipses through any combination of up to 30 drift spaces, quadrupole magnets, and constant field bending magnets with rotated pole faces. Particle trajectories or the beam envelope may be plotted for points every 20 cm. along the optic axis. The phase space ellipse at the exit of any beam element may also be plotted. The program does trajectory matching and ellipse matching to a waist or to a specified ellipse. It will also attempt to create an 'identity system'. The matching routines are based on a method for finding the minimum of a function of N variables without calculating first derivatives due to Powell. The program has been written in Fortran II and will run without modification on the IBM/360 digital computer.
