  In this paper we describe the methods and tools used to characterize a 150
MeV proton scaling Fixed Field Alternating Gradient (FFAG) accelerator at Kyoto
University Research Reactor Institute. Many of the techniques used are unique
to this class of machine and are thus of relevance to any future FFAG
accelerator. For the first time we detail systematic studies undertaken to
improve the beam quality of the FFAG. The control of beam quality in this
manner is crucial to demonstrating high power operation of FFAG accelerators in
future.
