NSLS-II Friday Lunchtime Seminar

"Delivering Focused, Rapidly Tunable, Stable Monochromatic X-Rays to the GSECARS APS 13-ID-E Microprobe Endstation"

Presented by Peter J. Eng, CARS and JFI, University of Chicago

Friday, November 9, 2018, 12:00 pm — NSLS-II Bldg. 743 Rm 156

With the APS-U scheduled for 2023 GSECARS, is designing and testing enhancements to beamline instrumentation to optimize the benefits of this upgraded source. The sector 13-ID-E microprobe endstation studies a wide range of environmental, earth and planetary problems, requiring a rich array of techniques and instrumentation. Central to the success of this program is the insertion device and the x-ray optics that produce, monochromate and focus the beam on the sample. All aspects of this system are under review. Design efforts are focused on 1) managing the increased total power and power density of the APS-U undulator source; 2) improved beam and sample stability; 3) improved focusing optics; and 4) rapid and high duty cycle scanning of the incident beam energy. This is an ongoing development effort with a number of enhancements schedule to be installed in the 1st quarter of 2019. Other components are in the design or prototype phase, drawing on collaboration between universities, national labs and industry.
