To demonstrate phase-space rotation technique, a six-cell FFAG ring has been constructed. The FFAG ring consists of full size of scaling-FFAG magnets which have been designed for muon phase rotation ring, and a high gradient rf cavity. For the six-cell experiment, six magnets has been aligned, and beam duct has been designed and installed. In this paper, it will be described about the construction procedure, apparatus, and measurement of magnetic field.
