The experimental setup for an NIS experiment on the P01 beamline at PETRA III with undulators (U), a high-heat-load double-crystal monochromator (DCM), horizontal cylinder parabolic Be compound refractive lenses (CRL1), the sample in the cryostat (S), rotationally parabolic Be compound refractive lenses (CRL2), the sapphire backscattering monochromator (BSM) crystal in the nitrogen gas-flow cryostat and avalanche photodiode detectors (Di, D16). The bottom scale shows the distances in metres from the source to the optical elements. |
