| Experiments Details | Beam line 4-3 is a wiggler side-station beam line for X-ray absorption spectroscopy and EXAFS measurements. This station enables tender X-ray measurement (S K-edge and up) and is setup with a He flight path from the beam line optics to the sample. The beam is collimated and unfocused to allow for high energy-resolution measurements on homogenous samples. 4-3 is equipped with a 4-element solid-state Si drift detector in addition to ionization chambers, PIPS and Lytle detectors. A liquid He cryostream allows for low-temperature measurements. A motorized sample holder stage allows sequential measurement on multiple samples without sample changeover delays. |
