Detailed Description


VarRadiusGeometry represents a Geometry with variable radius. Assuming
a Tanh model for fringe fields, the radius of curvature varies inversely
proportional with the fringe field. Such a magnet will follow the
trajectory of the reference particle. The origin is defined at the centre and extends from -length / 2 to
+length / 2. Transformations are calculated using a CoordinateTransformation object,
which integrates to find the reference trajectory.
