Possibilities for a Diffraction-Limited Upgrade of the Advanced Light Source

Speaker: Christoph Steier, Lawrence Berkeley National Lab
APS Upgrade Seminar
401/E1100 @ 10:00 AM
View Description
Improvements in brightness and coherent flux of about two orders of magnitude over currently operating storage ring based light sources are possible using multi bend achromat lattice designs. Such improvements can be implemented as upgrades of existing facilities, making use of the existing infrastructure, thereby reducing cost and time needed to reach full scientific productivity on a large number of beamlines. Some of the design choices for diffraction limited storage rings are impacted by the choice of spectral range for which the facility is designed. Specifically for soft x-rays it is possible to reach the diffraction limit in both planes with a ring of moderate size (200 m circumference) and beam energy (2 GeV) using round beams. Because of the strong energy scaling of intrabeam scattering, and photon beam heat load, as well as the energy scaling of achievable focal lengths for quadrupoles (and sextupoles), performance trade-off studies for such lower energy rings lead to some design choices different from facilities optimized for hard x-rays.

Probing the Nano World with EXAFS and XANES

Speaker: Dr. Soma Chattopadhyay, Illinois Institute of Technology
XSD Presentation
401/B4100 @ 11:00 AM
View Description
EXAFS (extended x-ray absorption fine structure) and XANES (x-ray absorption near edge structure) spectroscopy are powerful characterization tools and have broad applications in material science, biology, chemistry, physics, environment, geology, engineering and nanoscale materials. I have used the quick-EXAFS and quick-XANES facility at 10 ID beamline of APS to do in-situ studies of battery materials during their cycling process, in-situ chemical synthetic reactions and also ex-situ studies of quantum-dots, oxides and metal nanoparticles. I shall present my results on the following topics:

(a) Characterization of biomolecule - inorganic nano-hyrbrids : the case of Au core- Ag shell nanoparticles inside apoferritin protein.
(b) In-situ study of the growth mechanism of Mo-doped metallic Fe and hollow g-Fe2O3 nanoparticles.
(c) Role of Sr dopants in improving the mechanical properties of Al-Si eutectic alloys used in car engines.
(d) The lung bacteria Pseudomonas aeruginosa’s defense against quantum dots and released toxic materials.

Wide Bandgap (WBG) Semiconductor Power Devices for Switching and RF Power Supplies

Speaker: Krishna Shenai, Energy Systems Division
ASD Seminar
401/A1100 @ 9:00 AM
View Description
For nearly five decades, silicon has remained as the industry workhorse for solid-state electrical power switching and amplification. In the past three decades, there has been a concerted effort to develop Silicon Carbide (SiC) and Gallium Nitride (GaN) power semiconductor switching devices because of their potential for superior electrical and thermal performances compared to silicon power devices. This talk will discuss the current status and future trends in Wide Band Gap (WBG) power devices for switching and RF power supplies.
