FFAGs: (Fixed-field Alternating Gradient) New Directions in Accelerators: Accelerators are playing increasingly important roles in science, technology, and medicine, with demands for – higher beam currents, duty factors, and precision beam control, – All (of course) in the context of affordable and reliable technology. This drive has generated world-wide interest in FFAGs. FFAGs have the high repetition rates characteristic of cyclotrons, yet they embody the advantages of the synchrotron: high energy reach, long insertions- multiple ports, strong-focusing periodic lattice=high space charge tolerance variable energy, low losses, compact footprint, high energy reach, long insertions- multiple ports, strong-focusing periodic lattice=high space charge tolerance. Combining the best features of the cyclotron and synchrotron, FFAG accelerators represent new directions in accelerator science and are presently under international development.
