Description
Fixed Field Alternating gradient accelerators (FFA) hold
promise for pulsed high intensity applications. No such
FFA has been constructed to date; therefore a prototype -
the Front End Test Stand-FFA (FETS-FFA) has been pro-
posed to explore the feasibility of using FFA technology for
the next generation spallation neutron source, ISIS-II. A key
component of this prototype is its main magnets, which must
meet several critical requirements: maintaining zero chro-
maticity during acceleration, offering tune point flexibility,
and providing a large dynamic aperture. The selected lattice
incorporates a doublet spiral magnet design for more flexi-
ble operations in the tune space. The magnetic field profile
is generated by distributed conductors wound over the pole
face; a 3D analysis using OPERA software was conducted to
evaluate the settings necessary to produce the desired field.
The cell tune variation was found to be within ±0.0015 hor-
izontally and ±0.002 vertically, for four different working
tune points.
