The beamline ID13 is located in the main experimental hall, Sector 14-5. The beamline has two end stations that offer two distinct beam sizes: the micro-branch, and the nano-branch, each with a dedicated control room. At the beamline premises, there are two wet chemical labs, sample preparation facilities equipped with microscopes and sample handling tools, and a meeting room with tea and coffee available for the users.

Micro-branch experimental hutch (EH2)                                     Micro-branch control room            

The micro-branch is composed of the following elements (detailed information in the Technical information page):

• A set of tungsten slits, positioned upstream of the focusing optics, are used to cut in the monochromatic beam to adjust its size and position on the focusing lenses.

• The micro-beam is achieved using parabolic Be Compound Refractive Lenses (CRLs) in a transfocator mounted on an hexapod for precise alignment of the optical axis.

• An ionization chamber is positioned upstream the sample to measure the incoming beam intensity (I0).

• An aperture downstream is used to obtain a clean the beam without unwanted background scattering and diffusion.

• The sample can be raster scanned using stepper motors in the two axes perpendicular to the beam direction. A rotational stage can be integrated on top of the scanning stages for angular-dependent measurements, tomography, or diffraction experiments requiring sample rotation.

• A flight-tube filled with He gas can be added downstream the sample to reduce the air absorption and minimize background. The flight-tube can be equipped with photo-diodes to measure the back-scattered radiation and quantify the transmitted intensity (I).

• The directly transmitted beam is blocked by a lead beam-stop mounted on a glass needle. The beam-stop size can vary from 100 µm to 3 mm in thickness depending on the required conditions.  

• Different detectors can be placed at the back of the end-station depending on the technique used (SAXS, WAXS, XRF, ptychography...). The detectors can be positioned at varying distances up to ~ 2 m.

• An additional fluorescence detector can be placed laterally to acquire the X-ray fluorescence signal from the sample.

Nano-branch experimental hutch (EH3)                                       Nano-branch control room             

The nano-branch is composed of the following elements (detailed information in the Technical information page):

• A set of tungsten slits, positioned upstream of the focusing optics, are used to cut in the monochromatic beam to adjust its size and position on the focusing lenses.

• The nanobeam is achieved using multilayers Laue Lenses (MLLs) of different focal length. MLLs are chromatic optics and their focusing capabilities depend on the X-ray energy.

• An ionization chamber is positioned upstream the sample to measure the incoming beam intensity (I0).

• A 40 µm Platinum-Iridium square order separation aperture (OSA) is used to suppress unwanted diffraction orders coming from the diffractive lenses.

• A hexapod stage provides high-precision alignment for accurate positioning of samples and sample environments. The sample can be raster scanned using piezo-motors. A rotational stage can be integrated on top of the scanning stages for angular-dependent measurements, tomography, or diffraction experiments requiring sample rotation.

• A flight-tube filled with He gas can be added downstream the sample to reduce the air absorption and minimize background. The flight-tube can be equipped with photo-diodes to measure the back-scattered radiation and quantify the transmitted intensity (I).

• The directly transmitted beam is blocked by a lead beam-stop mounted on a glass needle. The beam-stop size can vary from 100 µm to 500 µm in thickness depending on the required conditions.  

• Different detectors can be placed at the back of the end-station depending on the technique used (SAXS, WAXS, XRF, ptychography...). The detectors can be positioned at varying distances up to ~ 3 m.

• An additional fluorescence detector can be placed laterally to acquire the X-ray fluorescence signal from the sample.
