Experimental end-stations
Classical XAS station: multi-element solid state detection
- Beam size: 100x300 µm2
- Energy range: 4.8 to 40keV
-
Detection systems:
- Transmission mode: diodes collecting photons scattered by air in a black chamber for both incident and transmited intensity measurements
- Fluorescence mode: 30-element Ge detector (resolution about 250eV for a total counting rate around 30 000 cts/s/elt)
- Sample environment: any system weighting less than 100 kg, with convenient windows. See Sample environments page.
High dilution XAS station: crystal analyser spectrometer
- Beam size: 100x300 µm2
- Energy range: 4.8 to 20keV
-
Detection system: 5-crystal analyser spectrometer (resolution about 1-2eV). The beamline possesses several types of crystals with 1m bending radius:
- Ge331 (5 cristals)
- Ge110 (3 crystals mid-April 2014)
- Ge111 (1 crystal)
- Ge422 (1 crystal)
- Si111 (diced, 1 crystal)
All crystals were provided by XRS Tech. Please see here the corresponding fluorescence lines. Contact us if you need another one.
- Sample environment: path between sample and crystals is under helium. Possible sample environments are limited. ESRF mini-cryostat (on the beamline) can be used, as well as heating systems such as gas blower furnace (from the ESRF environment pool). See Sample environments page.
Micro-beam XAS station
- Beam size: 10x10 µm2 obtained by a Kirkpatrick-Baez system.
- Energy range: 4.8 to 20 keV
- Detection system: Vortex SDD fluorescence detector
- Sample environment: possible sample environments are limited by the small available space. Diamond anvil cells can be used as well as heating systems such as Linkam ones. See Sample environments page.
