Abstract: A Double Multilayer Monochromator (DMM) was designed in-house for the VMXi beamline. This paper describes the novel engineering solutions employed to build a high stability instrument. PiezoMotor® actuators drive sine-arm Bragg axes for both optics providing the coarse and fine motion in a single actuator. The long translation of the second multilayer is driven externally via a linear shift to eliminate in-vacuum pipe & cable motions. A high stability air bearing translates the whole DMM across the two multilayer stripes. The optics are water cooled via an Indium / Gallium eutectic alloy bath to minimise coupled vibrations. The DMM is operational on the VMXi beamline, experimental and performance data is presented.
