We have fabricated an edge-focusing wiggler for FEL and SASE in the far-infrared region at the Institute of Scientific and Industrial Research (ISIR), Osaka University. We have adopted the strong focusing scheme for the wiggler in order to keep the beam size small along the wiggler. The period length of the wiggler is 60 mm, the number of periods is 32, and the total length is 1.938 m, including end magnet blocks for the orbit compensation. The wiggler consists of four FODO cells for double focusing. Focusing elements and defocusing elements are incorporate with single wiggler periods with edge angles of +5° and -5°, respectively, and they are separated by 3 normal wiggler periods. In this paper, we report fabrication of the strong focusing wiggler and results of the magnetic field measurement.
