An elliptical multipole wiggler (EMPW) based on a new concept has been installed on the SPring‐8 storage ring. The EMPW, with a 120 mm period, has a critical energy of 50 keV at a gap of 20 mm. It will provide high‐brilliance hard circularly polarized X‐rays in the 100–300 keV range to the pilot beamline dedicated to materials science: the Compton scattering beamline. Field measurements, field integrals, the expected fluxes, polarization rates, power and power densities are presented for two operating gaps: 30 mm during commissioning, 20 mm later.
