| Experiments Details | BL14-3 is a bending magnet side station for X-ray imaging and micro X-ray absorption spectroscopy of biological, material, and geological samples. Most often used for data collection at the sulfur K edge, BL14-3 is also capable of obtaining spectroscopy data at the phosphorous K edge. During imaging mode a Kirkpatrick-Baez (KB) mirrors system is used to achieve microfocus with a beam size of ~ 5 x 5 microns. BL14-3 is equipped with a Vortex silicon drift detector and ionization chambers for imaging. Sample positions are controlled with submicron accuracy by a Newport sample stage, inside a helium environment. BL14-3 is ideal for obtaining elemental maps of small samples (~ 20 microns to 25 mm) as well as performing spectroscopy on selected points in the sample (~5 x 5 microns). Bulk XAS can be performed on a separate in-hutch table using the upstream optics in focused or defocused configurations. Bulk XAS experiments employ either a 4-element Vortex detector or a large-area Canberra PIPS detector. A motorized multi-sample holder is available to allow queued data collection. |
