FFAG meaning in Academic & Science ?

Answer:

What is Fixed Field Alternating Gradient mean?

A Fixed-Field alternating gradient Accelerator (FFA) is a circular particle accelerator concept on which development was started in the early 50s, and that can be characterized by its time-independent magnetic fields (fixed-field, like in a cyclotron) and the use of strong focusing (alternating gradient, like in a synchrotron). Thus, FFA accelerators combine the cyclotron's advantage of continuous, unpulsed operation, with the synchrotron's relatively inexpensive small magnet ring, of narrow bore.

Although the development of FFAs had not been pursued for over a decade starting from 1967, interest has been revived since the mid-1980s for usage in neutron spallation sources, as a driver for muon colliders and to accelerate muons in a neutrino factory since the mid-1990s.

The revival in FFA research has been particularly strong in Japan with the construction of several rings. This resurgence has been prompted in part by advances in RF cavities and in magnet design.

We note that the acronym for Fixed-Field alternating gradient Accelerator has recently changed from FFAG to FFA. Thus, when searching older literature, one will find more often the original acronym of FFAG.
