DXR-1 Beamline Instrumentation The soft X-ray beamline is equipped with a Toyama flat double-crystal monochromator based on the 'boomerang' mechanism that ensures a fixed-exit beam while scanning the whole energy range that goes from 900 eV to about 3100 eV. 
The available energy range depends on the crystals used: | CRYSTAL | 2d (Å) | E min (eV) | E max (eV) | | Beryl (10-10) | 15.95 | 900 | 1800 | | KTP (011) | 10.95 | 1200 | 2100 | | InSb (111) | 7.481 | 1800 | 3100 | | Ge (111) | 6.532 | 2100 | 3100 |
Research activities and available detectors are mainly devoted to soft X-ray Absorption Spectroscopy (XAS) in particular X-ray Absorption Near Edge Spectroscopy (XANES) at the K edges of light elements like Na, Mg, Al ,etc. and on L and M edges of elements with higher Z values. The beamline is also equipped for tests on soft x-ray detectors and optics. |
