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.
一种基于新概念的椭圆多极波荡器（EMPW）已安装在SPring-8储存环上。该EMPW周期为120毫米，在20毫米的间隙下临界能量为50 keV。它将为专门用于材料科学的试验光束线——康普顿散射光束线，提供能量范围在100 - 300 keV的高亮度硬圆偏振X射线。文中给出了两个工作间隙下的场测量、场积分、预期通量、偏振率、功率和功率密度：调试期间为30毫米，之后为20毫米。
