2D simulation results: field distribution in DIP and DIPm magnet cross sections. The colour scale goes from 0 to 2 T. The main coil cross section is marked in grey. The field is highest over the inner leg of the main coil, ∼1.3 T. There is also local saturation of ∼1.8 T at the inner corner of the pole profile. Left: DIPm at NI = 6135 A, with B = −0.53334 T, B′ = 8.74833 T m−1 and B′′/2 = 1.41 T m−2 [by quadratic fit to simulated By(x) over x = ±11 mm]. Right: DIP at NI = 6120 A, with B = −0.52831 T and B′ = 8.65569 T m−1 [by linear fit to simulated By(x) over x = ±11 mm]. |
