| Experiments Details | Beam line 9-3 is a wiggler side-station beam line dedicated to biological X-ray absorption spectroscopy and EXAFS measurements of dilute solutions and single crystals. BL9-3 is equipped with a 100-element Ge monolith solid-state detector in addition to ionization chambers and Lytle detectors. A dedicated liq-He cryostat allows for routine low temperature measurements on solutions. A Huber-Kappa goniometer, a Liq-He cryostream, a focusing polycapillary and a MAR CCD detector are available (in addition to specialized software) for single crystal measurements. The higher flux, tighter focus and excellent beam stability on BL9-3 is ideal for very dilute samples and single crystals. |
