Model of Injection Channel Field map for dipole fringe field Wuzeng s map 710 cm < x < 719.5cm Inflector axis is at 718.9 cm => map ends at inflector axis + 0.6cm 2.5 cm < y < -2.5 cm 0 < z < 430 cm Approximation: If trajectory extends beyond the map boundary, use the value of B at the boundary. Inflector 1. Wuzeng s map (with 2.35 mrad tilt with respect to dipole fringe map) 711cm < x < 720.5cm (includes all points within inflector aperture) 2.5cm < y < -2.5cm (includes most of points in inf aperture [+-2.8mm]) 0 < z < 430 cm 2. Uniform map B is uniform throughout space. B_y ~ B_magic, B_x=B_z = 0. Note: Field maps extend from 30cm upstream of yoke through to end of inflector. The starting point for tracking propagation of twiss parameters in the next slides is 30cm upstream of the yoke. 8/13/14 D. Rubin 2
