PRISM is a next-generation of muon source which provides high purity, high intense and high brightness beam. In PRISM, a PRISM-FFAG is one of key section which make a muon beam narrow energy width by using phase rotation technique. To demonstrate the phase rotation, a six-cell FFAG ring has been constructed; the ring consists of full size of scaling-FFAG magnets and a high gradient rf cavity. The experiment is achieved by injecting alpha particles from a radioisotope source as a beam. Construction of the ring has been started from September, 2007; beam duct has been designed and installed, the six FFAG magnets has been aligned, etc. In this paper, we will present the design of the ring and the construction (alignment, etc) from engineering point of view.
