New HMI hard X ray diffraction beamlines at BESSY

Since April 2005 the Hahn Meitner Institute is operating two new beamlines for energy dispersive diffraction experiments EDDI and for resonant magnetic scattering MAGS at BESSY. The source for both beamlines is a superconducting 7 T multipole wiggler which provides hard X ray photons with energies between 4 and 150 keV. The EDDI beamline uses the white beam and is intended for residual stress measurements on small samples as well as heavy engineering parts.The MAGS beamline delivers a focussed monochromatic beam with photon fluxes in the 1012 s 100 mA 0.1 bandwidth 1 range at energies from 4 to 30 keV. It is equipped for single crystal diffraction and resonant magnetic scattering experiments as well as for the study of thin films, micro , and nanostructures in materials scienc
