Bending Radius of the kiwi dipole is 318.5 mm, and it bends beam by 45 degree.

The path of the beam in the dipole then [math] S = \rho \times \theta = 318.5 \times \pi/4 = 318.5 \times 3.14159265 / 4 = 250.149315~ mm[/math]

2nd Mapping

Bending radius of dipole is 319 mm. The bending radius in measurement is r = 280 mm.

Mapping of the dipole was divided into 3 parts according to the path of the ideal particle. This trajectory of particle with ideal energy should go through a fringe field (approximately straight line) and dipole field (rotation of near 45 degree with dipole bending radius of 319 mm), and another fringe field (approximately straight line). We called them A2 (entering fringe field), Rotation and A1 (Exiting fringe field).
