-
scaling Fixed Field Alternating Gradient)
accelerator


FFAG: Field fixed in time but varies across pipe





Nonscaling: Dipole field scales with momentum but focussing
quadrupole fields do not



Optics changes during acceleration


Betatron Tune changes during acceleration


Resonances unavoidable


But rapid acceleration means this is not fatal. (We hope)

Ring Magnets

Requirements /

Solution


Adjust dipole & quadrupole components
independently
-

Mount magnets on independent
radial linear slides



Fields identical in every cell despite kickers and
septum
-

Field clamps at cell entrance face of QD
& exit face of QF. Adjusted at the factory




Very large good field region for range of closed
orbits
-

Optimised pole profile implemented


Due to extreme compactness of lattice, D & F magnets


Are in very close proximity. Consequence: field
computation and measurement with both magnets
in place has been essential. Results from the
prototype measurements have been implemented
in the lattice simulations


Are short compared with aperture. Consequence:
integrated strength is dominated by end
