Project description

NanoMAX is a Hard X-ray monochromatic nanoprobe experimental station at MAX IV. The second experimental station at NanoMAX beamline use two plane-elliptical in Kirkpatrick-Baez configuration to achieve a spot size in the 100-1000 nm range. In order to meet the high demands of stability at MAXIV and high level of accuracy for the attenuation of the mirrors a in-house design was developed. The design is influenced by MAXIV alignment principle with one alignment unit per degree of freedom. Flexure links and a cage made from invar is the backbone of the design with low thermal drift. The mirror supports are designed to exclude the gravitational effect and the mirrors have a figure error of less than 1 nm.
