Abstract

The B16 Test beamline at the Diamond Light Source is in user operation. It has been recently upgraded with the addition of a double multilayer monochromator (DMM), which provides further functionality and versatility to the beamline. The multilayer monochromator is equipped with two pairs of multilayer optics (Ni/B₄C and Ru/B₄C) to cover the wide photon energy range of 2 - 20 keV, with good efficiency. The DMM provides a broad bandpass / high flux operational mode for the beamline and, when used in tandem with the Si (111) double crystal monochromator, it gives a very high higher-order harmonics suppression. The design details of the DMM and the first commissioning results obtained using the DMM are presented.
