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 |
At the DXR1 beamline Xray Absorption Fine Strucure or XAFS spectroscopy measurements can be performed in absorption and fluorescence mode.
