2. Initial data Integral field non-uniformity – ΔʃB dl/ ʃ B dl = ±1·10-4
Local field non-uniformity – ΔB/B = ±1·10-3
Lamination thickness <2mm
Magnet to magnet identity = ±5·10-4

3. Decisions H-type magnet RaceTrack Coils Straight
Geometry parameters
Packing factor
Yoke and coils manufacturing cost
Punched lamination from M A
Lamination thickness 1mm – possible punching with acceptable tolerances and packing factor about 98%
