Welcome to Surface and Interfaces

The Surface and Interfaces village brings together six beamlines with a range of techniques for investigating structural, magnetic and electronic properties of surfaces and interfaces.

Beamlines -
I05 ARPES

I05-ARPES is a facility dedicated to the study of electronic structures of solids and their surfaces by Angle-Resolved Photoemission Spectroscopy (ARPES). The ultrahigh vacuum low temperature high resolution ARPES end station is served by an intense, highly monochromatic VUV to XUV photon beam from a variable polarisation Apple II undulator.

Beamsize: < 100 microns

Energy: 18 - 240 eV;

Wavelength: 60 - 5 nm; 2.5 nm

Detector: VG Scienta R4000 analyser

I06 Nanoscience

I06 is a polarised spectroscopy and microscopy beamline equipped with a PEEM, 6T low temperature (1.5K) superconducting magnet, 2T vector magnet as well as soft x-ray diffraction vacuum goniometer.

Energy: First harmonic circular: 106 - 1300 eV | Linear Horizontal: 80 - 2100 eV | Linear Vertical: 130 - 1500 eV

I07 Surface and interface diffraction

I07 is a high-resolution X-ray diffraction beamline for investigating the structure of surfaces and interfaces under different environmental conditions, including, for example, semiconductors and biological films. 

Beamsize: 200µm x 300µm

Energy: 6-30 keV

Wavelength: 0.4-2.0Å

Detector: Pilatus 100K, Pilatus 2M, Cyberstar, APD

B07 Versitile Soft X-ray

B07 will be a highly versatile soft x-ray beamline for NEXAFS/XPS suitable for studies of heterogenous catalysis, pharmaceuticals & biomaterials under realistic conditions, electronic & photonic materials, atmospheric & space science on liquids/ices and heritage conservation.

Beamsize: 48 μm (H) × 21 μm (V) - TBC

Energy: 50 - 2800 eV

Wavelength: 24.8 - 0.44 nm

Detector: TBD

I09 Surface and Interface Structural Analysis

I09 is designed to provide both soft and hard X-rays for high-resolution studies of atomic and electronic structures of surfaces and interfaces using photoelectron spectroscopy, near edge X-ray absorption fine structure, X-ray standing waves and photoelectron diffraction.

Beamsize: 30 µm (H) x 15 µm (V), defocusing possible

Energy: 100 - 2100 ev, 2.1 - 20 keV

Detector: VG Scienta EW4000, Photodiodes

I10 Advanced Dichroism Experiments

I10 is a beamline for the study of electronic and magnetic structure using soft X-ray resonant scattering (reflection and diffraction) and X-ray absorption. It allows a broad range of studies focused on the spectroscopic properties and magnetic ordering of novel nanostructured systems

Beamsize: 200 x 20 µm

Energy: 500-1600 eV

Detector: Photodiode, Channeltrone
