Common Coil Design
Simple 2-d geometry with large bend radius (determined by spacing between two apertures, rather than aperture itself)
Conductor friendly (no complex 3-d ends, suitable for brittle materials - most for H.F. are - Nb3Sn and HTS)
Compact (quadrupole type cross-section, field falls more rapidly)
Block design (for handling large Lorentz forces at high fields)
Combined function magnets possible
Efficient and methodical R&D due to simple & modular design
Minimum requirements on big expensive tooling and labor
Lower cost magnets expected
