Probing a Battery Electrolyte Drop with Ambient Pressure Photoelectron Spectroscopy
ARTICLE https://doi.org/10.1038/s41467-019-10803-y OPEN Probing a battery electrolyte drop with ambient pressure photoelectron spectroscopy Julia Maibach 1,2, Ida Källquist 3, Margit Andersson4, Samuli Urpelainen 4, Kristina Edström1, Håkan Rensmo3, Hans Siegbahn3 & Maria Hahlin 3 Operando ambient pressure photoelectron spectroscopy in realistic battery environments is a key development towards probing the functionality of the electrode/electrolyte interface in 1234567890():,; lithium-ion batteries that is not possible with conventional photoelectron spectroscopy. Here, we present the ambient pressure photoelectron spectroscopy characterization of a model electrolyte based on 1M bis(triﬂuoromethane)sulfonimide lithium salt in propylene carbonate. For the ﬁrst time, we show ambient pressure photoelectron spectroscopy data of propylene carbonate in the liquid phase by using solvent vapor as the stabilizing environment. This enables us to separate effects from salt and solvent, and to characterize changes in elec- trolyte composition as a function of probing depth. While the bulk electrolyte meets the expected composition, clear accumulation of ionic species is found at the electrolyte surface. Our results show that it is possible to measure directly complex liquids such as battery electrolytes, which is an important accomplishment towards true operando studies. 1 Department of Chemistry – Ångström Laboratory, Uppsala University, Box 538, 751 21 Uppsala, Sweden. 2 Institute for Applied Materials (IAM), Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany. 3 Department of Physics and Astronomy, Uppsala University, Box 516, 751 20 Uppsala, Sweden. 4 MAX IV laboratory, Box 118, 221 00 Lund, Sweden.

Proceedings of the 2017 CERN–Accelerator–School course on Vacuum for Particle Accelerators, Glumslöv, (Sweden) Brief Introduction to Particle Accelerators P. F. Tavares MAX IV Laboratory, Lund, Sweden Abstract This lecture is a brief introduction to charged particle accelerators. The aim is to provide the reader with basic concepts and tools needed to describe the motion of charged particles under the action of guiding and focussing ﬁelds, with an emphasis on those aspects that are relevant to understanding and quan- tifying how accelerator vacuum systems affect accelerator performance. Even though the focus is on electron accelerators and, in particular, electron storage rings used as synchrotron light sources, most of the concepts described are of general application to a wider class of particle accelerators. Keywords Particle accelerators; electron beam optics; Twiss parameters. 1 Assumptions and Goals In writing these notes, I have assumed that the reader is familiar with relativistic mechanics and elec- tromagnetic theory at the advanced undergraduate or beginning graduate level. I have not assumed any previous knowledge of accelerators or charged particle beam dynamics. The aims of this lecture are: 1. to provide motivations for developing and building particle accelerators; 2. to describe the basic building blocks of a typical particle accelerator; 3. to describe the basic concepts and tools needed to understand how the vacuum system affects accelerator performance. Caveat: I will focus the discussion/examples mostly concerning one type of accelerator, namely electron storage rings optimized as sources of synchrotron radiation, although most of the discussion can be translated into other accelerator models. The interested reader can ﬁnd all of the material presented here discussed at length in a number of by now classical references.

Beamline Status MAX IV September 2020
DNR: STYR 2020/725-3 Status of beamlines at MAX IV September 2020 Status of MAX IV MAX IV accelerators are performing well, and all three deliver X-ray light to beamlines. Fourteen beamlines are currently taking light, four of which are in commissioning and ten in general user operation. The Covid-19 pandemic has had a dramatic impact on research activities globally. Despite this challenging environment, MAX IV accelerators and beamlines continue to operate according to schedule. The principal impact of the pandemic on research at MAX IV is that most users have not been able to come to MAX IV for their scheduled beamtime. MAX IV users have cancelled about 30 user projects since the last report.1 Nevertheless, all beamlines are working together with their users to find solutions to serve them under these unprecedented circumstances. Several beamlines, e.g. BioMAX, Balder, MAXPEEM, and NanoMAX, are serving users remotely with mail-in samples. In order to support science towards understanding the SARS-CoV-2 virus-related disease, and to bring us closer to an effective vaccine, diagnostics or treatment, MAX IV offers its instrumentation and beamtime through a rapid access mode to facilitate these efforts. Two user groups have utilised rapid access mode so far. The first results have been analysed and are about to be submitted for publication. MAX IV will reschedule users who could not use beamtime scheduled during the spring 2020 cycle due to the pandemic for beamtime in the upcoming autumn 2020 cycle. In addition, MAX IV will extend this cycle to allocate beamtime to highly ranked proposals in the spring call.

Approach of Serial Crystallography II
crystals Editorial Approach of Serial Crystallography II Ki-Hyun Nam Department of Life Science, Pohang University of Science and Technology, Pohang 37673, Gyeongbuk, Korea; [email protected] Abstract: Serial crystallography (SX) is an emerging X-ray crystallographic method for determining macromolecule structures. It can address concerns regarding the limitations of data collected by conventional crystallography techniques, which require cryogenic-temperature environments and allow crystals to accumulate radiation damage. Time-resolved SX studies using the pump-probe methodology provide useful information for understanding macromolecular mechanisms and struc- ture ﬂuctuation dynamics. This Special Issue deals with the serial crystallography approach using an X-ray free electron laser (XFEL) and synchrotron X-ray source, and reviews recent SX research involving synchrotron use. These reports provide insights into future serial crystallography research trends and approaches. Serial crystallography (SX) experiments using an X-ray free electron laser (XFEL) with a short pulse width, or short time X-ray (<100 ms) exposure in a synchrotron, minimize ra- diation damage to crystals compared with traditional X-ray crystallographic methods [1,2]. Moreover, SX data collection at room temperature provides more biologically reliable data on structural dynamics in macromolecules compared to cryo-crystallographic tech- niques [3–5]. In addition, in SX data collection, if a crystal sample is stimulated with a pump, such as an optical laser or a ligand/inhibitor solution, and then diffraction data are collected by exposure to X-rays after a selected time delay. This can time-resolve molecu- lar mechanisms of macromolecules [6,7]. Thus, SX techniques provide more biologically Citation: Nam, K.-H.

Evaluation of the Modified Max Iv Proposal 2009
Synchrotron radiation is today a versatile and widespread scientific tool. The MAX-laboratory in Lund has proposed a new synchrotron radiation facility, named MAX IV, intended to deliver spontaneous as well as coherent radiation of very high quality over a broad spectral range. The technical design and scientific case of the proposal were evaluated in 2005 and 2006 and indicated that the proposed MAX IV facility would offer a world leading and unique light source of importance to competitive science in a wide range of scientific disciplines. Since then, preparations have been made for the construction of the MAX IV facility, including drafting of a modified technical design of the facility in order to better meet upcoming user needs. A panel of international experts has scrutinized the new technical design of MAX IV and their conclusions and recommendations are presented in this report.
