Below two examples of a `SBEND3D` which loads a field map file named “90degree_Dipole_Magnet.out” defining a hard edge model of 90 degree dipole magnet with homogenous magnetic field. The first 8 lines are presumed to be header material and are ignored. The first 8 lines in the field map are ignored. Positions have units of m and fields units of Tesla. The corresponding 3D magnetic field map is shown in the following figure in the Cartesian coordinate system (x, y, z). A horizontal cross section of the 3D magnetic field map when z = 0 is also shown.
SBEND3D assumes a dipole symmetry. In a dipole symmetry, fields below the symmetry plane Z=0 have the same field in the direction perpendicular to the symmetry plane, latexmath:[B_{z}], but field components parallel to the symmetry plane have the opposite direction (sign).
