Abstract

NanoMAX is the first hard X-ray nanoprobe beamline at the MAX IV laboratory. It utilizes the unique properties of the world's first operational multi-bend achromat storage ring to provide an intense and coherent focused beam for experiments with several methods. In this paper we present the beamline optics design in detail, show the performance figures, and give an overview of the surrounding infrastructure and the operational diffraction endstation.

Highlights

  • Scanning hard X-ray microscopy (SXM) offers methods for structure, morphology and composition studies of heterogeneous sample systems

  • SXM is utilized in material science, life science, cultural heritage, environmental science, nanotechnology and archaeology (Mino et al, 2018; Hemonnot & Koster, 2017; Cotte et al, 2018)

  • A laboratory dedicated to sample preparation for NanoMAX users is located at the end of the satellite building

Summary

Introduction

Scanning hard X-ray microscopy (SXM) offers methods for structure, morphology and composition studies of heterogeneous sample systems. The methods are either based on coherence to achieve spatial resolution, such as in ptychography or coherent diffraction imaging (CDI), or on the focused beam providing spatial resolution, such as in scanning diffraction or X-ray fluorescence (XRF) mapping experiments. The beamline will have two endstations to allow for diverse experimental requirements regarding sample environment, energy range, resolution or detector configuration. The diffraction endstation, brought into operation in 2017, exploits the intense coherent photon flux, uses Kirkpatrick–Baez (KB) mirrors for focusing to 40–200 nm and is designed to allow for bespoke sample environments and detector configurations. The beamline is 103 m long and extends out of the main experimental hall into a satellite building
