Advantages of Common Coil Magnet System with 4 Apertures (2-in-1 Accelerator)
~150 instead of usual 8-20.
May eliminate the need of the second largest ring. Significant saving in the cost of VLHC accelerator complex.
Low Field: Iron Dominated
High Field: Conductor Dominated.
Good field quality from injection to highest field with a single power supply.
As compared to single aperture D20,
4 apertures in less than half the yoke.
Beam is transferred, not injected
Minimum field seen by high field
aperture is ~1.5 T and not ~0.5 T.
The basic machine criteria are changed!
Can high field aperture be reduced?
Reduction in high field aperture =>
reduction in conductor & magnet cost.
