NSLS-II Seminar
"X-ray spectroscopy of transition metal oxides"
Presented by Frank de Groot, Utrecht University, Netherlands, Netherlands
11 am, NSLS-II Building 744 Room 156
Thursday, August 23, 2018, 11:00 am
Hosted by: Lisa Miller
Some new developments in x-ray absorption (XAS) and resonant inelastic x-ray scattering (RIXS) will be discussed. An introduction is given of XAS, including the oxygen K edge, metal K edge and metal L edge [1,2]. The main part of the talk deals with resonant inelastic x-ray scattering (RIXS) In 2p3d RIXS one scans through the 2p XAS edge and measures the low energy excitations, including phonons, magnons, dd-excitations and charge transfer. The 100 meV resolved 2p3d RIXS spectra of ruby (Cr3+ in Al2O3), Fe3O4 and LaCoO3 will be discussed [3,4]. The present experimental resolution of 30 to 100 meV allows the detailed observation of the electronic structure, including the determination of crystal field parameters, covalency parameters and spin-orbit coupling, but also the momentum dependence of magnons and other low energy excitations. Related to the RIXS measurements is the analysis of Fluorescence yield (FY) detected x-ray absorption spectra (XAS), including the intrinsic deviations of FY-XAS spectral shape from the XAS spectrum that is important for measurements with x-ray free electron lasers [5,6]. —————————————————————————— [1] Core Level Spectroscopy of Solids Frank de Groot and Akio Kotani (Taylor & Francis CRC press, 2008) [2] Download the x-ray spectroscopy simulation software at http://www.anorg.chem.uu.nl/CTM4XAS/ [3] Huang et al.

NSLS-II Colloquium Series
"Mulling over Nanoemulsions: Interfacial Molecular Structure, Stabilization and Assembly"
Presented by Prof. Geraldine (Geri) Richmond, University of Oregon
Thursday, August 9, 2018, 4 pm
Large Seminar Room, Bldg. 510Hosted by: John Hill
Nanoemlusions are finding numerous applications in the fields of pharmaceuticals, food production, materials synthesis and cosmetics. With the search for broader and improved usage of these unique droplets comes the need to better understand the molecular interactions at the surface that lead to their stabilization. This presentation will focus on our most recent efforts in measuring the molecular structure of the oil-water interface and the unique environment it provides for adsorption of molecules, surfactants and macromolecules at both planar and nanoemulsion oil/water interfaces. The studies are a combination of spectroscopic and thermodynamic measurements coupled with theoretical simulations.

NSLS-II Seminar
"Understanding microstructure evolution in lithium battery electrodes through coupled modeling and experiments"
Presented by Ming Tang, Dept of Materials Science & NanoEngineering, Rice University, Houston, TZ
Monday, May 7, 2018, 11 am
NSLS-II Bldg. 744 Room 156Hosted by: Yong Chu & Jun Wang
Like most materials, there exist very rich microstructure evolution phenomena in lithium battery electrode compounds during battery operation. Elucidating such phenomena through combined modeling and characterization including synchrotron-based techniques could yield valuable insights on how electrode structure should be designed and tailored at the mesoscale to enable stepwise improvement in battery performance. In this talk, I will first present our recent study on the unique aspects of phase transformation kinetics in Li-ion battery electrodes, using LiFePO4 as a model system. Through combined phase-field modeling and transmission x-ray microscopic observation of Li deintercalation process in LiFePO4 microrods, we discovered that intercalation-induced phase transformations can proceed in several distinct kinetic modes with varied electrochemical conditions and particle geometry. In particular, a hybrid mode, in which phase growth is surface-reaction-limited or bulk-diffusion-limited along different directions, is revealed for the first time. In the surface-reaction-limited transformation regime, we predict a surprising effect of antisite defects on accelerating phase boundary migration velocity by two orders of magnitude over defect-free LiFePO4 due to defect-induced increase in the surface reaction area. This finding suggests defect engineering as a fruitful approach to enhance the rate performance of intercalation compounds. The second part of this talk concerns the fundamental mechanism of dendrite growth on Li metal surface during electroplating, which presents a major challenge to the adoption of Li metal anodes in rechargeable batteries. Combining Li electroplating experiments and modeling, we obtained a key insight that Li dendrite growth is a stress-driven process, which is initiated by the compressive residual stress developed in deposited Li during battery cycling. Accordingly, elimination of the plating stress, e.g. via the use of soft substrate for Li

Presented by William (Bill) David, University of Oxford, United Kingdom
Thursday, April 12, 2018, 4 pm
Physics Bldg. 510 Large Seminar RoomHosted by: John Hill
Our increasing dependence on intermittent renewable energy production places a greater focus on the development of novel, affordable energy storage. The recent emphasis on electrochemical storage, and on lithium batteries in particular, addresses a significant component of our future energy storage requirements but future low-carbon energy scenarios must utilise a broad range of storage options. This talk will focus on several examples the underline the role that synchrotron X-ray and neutron powder diffraction can play in the understanding of both electrochemical and chemical energy storage systems.

"Development of insertion devices at SOLEIL"
Presented by Marie Emmanuelle Couprie, SOLEIL, France
Thursday, January 11, 2018, 4 pm
Large Seminar Room, Bldg. 510Hosted by: John Hill
Insertion devices (undulators and wigglers) are essential components for accelerator based light sources, such as synchrotron radiation facilities implemented on storage rings and free electron lasers. The wide panoply of insertion devices developed at Synchrotron SOLEIL (electromagnetic, combined permanent magnet and electromagnetic for rapid switching of the polarization, permanent magnet APPLE-II, hybrid in-vacuum and cryogenic undulators, out and in-vacuum wigglers) enables to cover a very wide spectral range (from the UV to the hard X-rays), and to provide flexibility for the users of the SOLEIL third generation light source. Starting from the description of the developments carried out at SOLEIL on the different types of systems, some future perspectives will be given, considering the evolution of the specifications of the different light source types. The use of the undulator radiation for photon beam based alignment and adjustment (such as taper) will be discussed. Furthermore, undulator radiation can serve as an electron beam diagnostic and provide a further insight on the electron beam quality itself, as illustrated in the case of the COXINEL project, using laser plasma acceleration.

Presented by Rob Lamb (CEO) and Dean Chapman (Science Director), Canadian Light Source, Canada
Wednesday, December 13, 2017, 11 am
NSLS-II, Bldg. 745Hosted by: Qun Shen
The Canadian Light Source (CLS) began operations in 2005 with 7 beamlines. Now a dozen year later, the last of 22 beamlines are in the final stages of construction. The ring is now almost completely filled with only one straight remaining. As the second decade of the CLS begins and the CLS matures, a new strategic plan focuses on using our most precious resource – the staff – to be more engaged in helping solve problems of societal importance. Some aspects of this plan and unique highlights from the facility such as agricultural and medical imaging research will be discussed.

"Introduction to NSLS-II Survey and Alignment"
Chenghao Yu, Brookhaven National Laboratory
Tuesday, December 12, 2017, 2 pm
John Dunn Seminar Room, Bldg. 463Hosted by: Sushil Sharma & Steven Hulbert
NSLS-II at Brookhaven National Laboratory is one of the newest and most advanced synchrotron facilities in the world. The accelerator and beamline components of this machine require very precise alignment to meet their performance requirements. For example, the alignment tolerance of magnets on a common girder of the storage ring is ± 30 µm and adjacent girders need to be aligned to within ± 100 µm. The precise alignment of the machine must be maintained throughout its lifetime. The alignment philosophy and processes, which are based on primary/secondary survey networks and modern laser trackers, will be discussed. The use of vibrating wire technique for a more precise alignment of the magnets will be described. Several "lessons–learned" examples will be presented to highlight good alignment practices and procedures. The Survey and Alignment group members, who are ready to support all survey and alignment requests across the lab, will be introduced.

"Imaging dynamics of radiation-sensitive molecules."
Presented by John Spence, Physics, Arizona State University, Tempe, AZ
Thursday, November 9, 2017, 4 pm
Large Seminar Room, Bldg. 510Hosted by: John Hill
The possibility of out-running radiation damage by the "diffract-and-destroy method, using femtosecond pulses of either electrons or hard X-rays, opens completely new vistas for imaging molecular dynamics at atom resolution and sub-picosecond speeds (1). First, I'll compare high-energy electron beams for this purpose, and compare them in regard to damage mechanisms and time-scales with XFEL radiation. I'll suggest a fast mode of image formation which provides high resolution despite the use of the large incoherent photocathode. I'll then review our work using the hard X-ray pulsed laser at SLAC within our BioXFEL 6-campus NSF consortium (http://www.bioxfel.org), aimed at the application of X-ray lasers (XFELs) to Structural Biology. I'll show molecular movies from light-sensitive proteins with 150 fs time resolution and near-atomic spatial , using both crystals and solution scattering obtained from the LCLS XFEL at SLAC, and very recent single-particle virus images (one virus per shot) showing dynamics. I'll discuss work in my lab on methods for hydrated sample delivery for an XFEL, and the compact IC XFEL under construction on the ASU campus, which uses a laser as an undulator. Finally, I'll review a recent proposal for the use of intensity interferometry to analyze the angular dependence of inner-shell X-ray fluorescence from a molecule.

"From single atom magnets to ultrafast switching: Insights from x-ray absorption spectroscopy and microscopy"
Presented by Pietro Gambardella, Department of Materials, ETH Zurich, Switzerland
Thursday, October 12, 2017, 4 pm
Large Seminar Room, Bldg. 510Hosted by: John Hill
What is the smallest possible size of a magnet? How fast can we switch the magnetization of a thin film? The answer to these simple questions reveals a fascinating world of interactions, which are largely dominated by interface effects. Understanding and controlling such interactions opens new perspectives for classical and quantum data processing technologies at the microscopic scale. Synchrotron radiation measurements exploiting x-ray dichroism at the L- and M-edges of the transition metal and lanthanide elements, respectively, provide a unique spectroscopic and microscopic tool to link the nanoscale properties of matter to the magnetic behavior of different classes of materials. In this talk, I will describe our studies of the evolution of magnetism from single atoms to nanoparticles and molecular magnets [1-4], focusing on the conditions required to achieve magnetic bistability in small systems [5,6]. I will further report on recent efforts to induce magnetization switching using electrical currents in materials characterized by strong spin-orbit interactions [7,8]. Current pump/x-ray probe experiments reveal the mechanism and time scale of magnetization reversal induced by the spin–orbit torques and spin Hall effect in thin film heterostructures, which has applications in ultrafast magnetic random access memories with high endurance [9,10].

"Front Ends and Insertion Devices for APS Upgrade"
Presented by Mohan Ramanathan, Argonne National Laboratory
Thursday, October 5, 2017, 2 pm
Bldg 744 Room 156Hosted by: Sushil Sharma
The Advanced Photon Source (APS) Upgrade Project is a major redesign of the current operating machine to a new multi-bend low emittance lattice operating at 6 GeV with 200 mA of stored beam. To fully support the APS Upgrade (APS-U), the front ends and insertion devices (IDs) located inside the storage ring tunnel need to be upgraded. Most of the front ends at the APS were designed more than 20 years ago and have limitations in the power handling capability. As part of APS Upgrade all the ID front ends will be replaced to one of two types – capable of handling the full straight section of IDs or canted with two ID beams. At the current time, the APS has 54 IDs in operation over 33 beamlines. Most of the devices were optimized more than 20 years ago for 7-GeV operation, providing full energy tunability in the hard x-ray range. To maximize the brightness and flux for all the beamlines (also part of the APS-U), most of the IDs will be replaced. This seminar will provide an overview of the plans for the front ends and insertion devices for the APS-U.

"Bridging The Gaps Between Mechanical Engineering, Electrical Engineering, and Motion Control for NSLS-II"
John Escallier, Brookhaven National Laboratory
Tuesday, September 12, 2017, 2 pm
John Dunn Seminar Room, Bldg. 463Hosted by: Sushil Sharma and Mary Carlucci-Dayton
Mechanical design constraints in many cases can present difficult and unintended motion control challenges in many instruments such as frontend slits, insertion devices, mirrors and monochromators. Design decisions for meeting science requirements often times introduce control stability issues that seldom arise in non-scientific equipment. The Delta Tau motion system is an extremely versatile platform for this control, but also presents a severe learning curve as a result of the versatility. This presentation will demonstrate how subtle geometry effects can create large control problems, and how to look for those subtle "opportunities."

"On the assessment of radiation damage and high temperature effects in novel nuclear materials using the BNL accelerators and synchrotrons"
Presented by Nick Simos, Sr Scientist Emeritus, BNL
Friday, September 8, 2017, 3 pm
Large Seminar Room, Bldg. 510Hosted by: Ron Pindak
In search for new and improved materials, composites and super-alloys capable of withstanding the anticipated extreme states associated fusion reactors; high temperature fast reactors and multi-MW particle accelerators, novel reactor steels, super-alloys and composites are continuously being explored to help meet both the challenge of the higher demand environments and the intended application. Higher fluxes and fluences of irradiating species (neutrons and/or protons), extreme temperatures and aggressively corrosive environments make up the new cocktail of operating conditions of the new array of material structures. One of the challenges in characterizing the effects that high radiation fluxes of neutrons and protons induce on these novel material structures in conjunction with high temperatures is the link between lattice induced damage and phase transformation and macroscopic physical properties which ultimately determine performance in the real environment. High energy X-rays at the BNL synchrotrons have offered a path in establishing this important connection between micro-scale effects and physical properties of novel material structures exposed to high radiation fluxes. Specifically, by integrating the unique capabilities of the BNL accelerator complex that includes, in addition to the NSLS and NSLS II, the proton accelerator and Tandem as well as those of CFN, the evolution and/or damage of materials ranging from classical structures such as graphite, beryllium and steels to novel super-alloys, such as those of Invar and "Gum" metal, and new composites have been characterized both at the two length scales. The pivotal role of high energy X-rays from NSLS to NSLS II in making the connection will be presented demonstrating the enormous potential of the NSLS II in answering fundamental questions in our path towards the next generation nuclear materials. Furthermore, first glimpses of the correlation of lattice effects or damage induced by differ
