I19 Small Molecule Single Crystal Diffraction
Status: Operational
Wavelength: 0.5 - 2.5 Å
Energy: 5 - 25 keV
Energy: 5 - 25 keV
| Energy range: | 5* to 25 keV 0.5 to 2.5* Å |
| Energy resolution (ΔE/E): | < 2 x 10-4 |
| Energy stability (ΔE/E): | < 4 x 10-5 |
| Flux @ 12.4 keV at sample 10-4 bandpass: | 1012 ph/s in 100 μm x 100 μm |
| Beam minimum size at sample position 1 (FWHM): | 50 μm x 50 μm |
| Beam minimum size at sample position 2 (FWHM): | 100 μm x 100 μm |
| Beam divergence @18 keV at sample: | < 400 μrad (h) x 50 μrad (v) |
* the very low energies in this range are dependent on a 5 mm undulator gap being achieved
