It offers unique possibilities for extracting simultaneously elemental, chemical, magnetic and electronic information at single digit nanometer spatial resolution to users from a wide area of research fields.

Specifications for MicroMAX

MicroMAX is a macromolecular crystallography beamline with emphasis on serial crystallography and time-resolved methods. It is flexible both in terms of X-ray beam properties and experiment setup. Automated crystallography with a high-capacity sample changer will be available when opening for users in spring 2023 with different serial and time-resolved methods becoming available in parallel.

Specifications for NanoMAX

NanoMAX is a hard X-ray beamline for imaging and diffraction studies at the nanoscale. The instrument provides coherent and highly focused X-rays at its two endstations.

Specifications for SoftiMAX

SoftiMAX is a soft X-ray imaging beamline with two branch lines. The first branch line is open for users who want to study the morphology, chemical and/or magnetic states of compounds in their samples on a microscopic level (<100 nm). The branchline is set up for transmission measurements, requiring thin (0.1-2 micron) samples.

Specifications for SPECIES

SPECIES is a soft X-ray beamline for ambient pressure XPS (APXPS) and resonance inelastic X-ray scattering (RIXS) experiments. The beamline offers a wide photon energy range (30-1500 eV) with different polarizations reaching even to the VUV range. For both endstations, multiple sample environments are offered.

Specifications for Veritas

Veritas is a high resolution Resonant Inelastic X-ray Scattering beamline for the soft X-ray region (250 – 1500 eV). The end-station is designed for high versatility with planned sample environments ranging from solids, in-situ and in-operandi conditions to gas-phase and liquids. The beamline also features an open port branch.

Specifications for the electron guns

The MAX IV linac serves two purposes: it’s a continuous top-up injector to both storage rings, but it also accelerates and compresses electron bunches for the short-pulse facility. The linac consists of two electron guns (a photo-rf gun for SPF pulses and a thermionic rf gun for storage ring injection), two bunch compressors, and 39 S-band accelerating structures along with their power stations (modulators, klystrons, SLED cavities). Two vertical transfer lines connect the linac with the two storage rings.

Specifications for the 1.5 GeV ring

The MAX IV 1.5 GeV storage ring is based on a compact double-bend achromat lattice for the production of bright soft x-ray and UV radiation. The storage ring is a redesigned and improved version of the decommissioned MAX II storage ring. The MAX IV 1.5 GeV storage ring has a circumference of 96 m, comprises 12 achromats (2 more than MAX II) of which 10 provide roughly 3.5 m straight sections for insertion devices (IDs). The compactness of the lattice is achieved by using the same magnet technology as in the 3 GeV storage ring where many smaller magnets are machined from common iron yokes. In addition, most magnets are combined-function type, i.e. the dipoles contain a vertically-focusing gradient and the horizontally-focusing quadrupoles contain a sextupole gradient.

Specifications for the 3 GeV ring

The MAX IV 3 GeV storage ring is based on a novel multibend achromat lattice for the production of ultra-bright hard x-ray radiation. The storage ring has a circumference of 528 m, comprises 20 achromats, and provides 19 straight sections of roughly 5 m length for insertion devices. The ultra-low emittance is the result of the strong focusing provided by the multibend achromat lattice. A fully NEG-coated copper vacuum system and highly compact magnets machined from common iron yokes provide the technical basis for the realization of this optics. The 3 GeV storage ring is the workhorse of the MAX IV facility and was the world’s first multibend achromat light source.
