Application of Ion Beam Analysis in Studies of First Wall Materials in Controlled Fusion Devices | Review by Marek Rubel, Anna Widdowson, Laura Dittrich, Sunwoo Moon, Armin Weckmann and Per Petersson https://lnkd.in/gPcTPdKY MDPI; Royal Institute of Technology; Culham Centre for Fusion Energy #ionbeam #Fusion #plasma #WallMaterial #physics #openaccess #Abstract The paper provides a concise overview of ion beam analysis methods and procedures in studies of materials exposed to fusion plasmas in controlled fusion devices with magnetic confinement. An impact of erosion–deposition processes on the morphology of wall materials is presented. In particular, results for deuterium analyses are discussed. Underlying physics, advantages and limitations of methods are addressed. The role of wall diagnostics in studies of material migration and fuel retention is explained. A brief note on research and handling of radioactive and beryllium-contaminated materials is also given.

💿 Phase change memory (PCM) technology is seen as the future of data storage. The challenge with PCM is ensuring that data stored in the device remains intact during operation, when the temperature rises. Summary of research published in the Journal of Applied Physics (AIP Publishing) has been recently added to the ‘China’s Research Excellence’ Showcase on Kudos. The concern is that at high temperatures, PCM devices that use Ge2Sb2Te5 (GST) would struggle to keep stored data intact. 🔗 Read the full summary through the link in the comments to learn how authors investigated how carbon doping could affect the atomic structure of GST and make it more stable. #physics #appliedphysics

Nanosecond plasmas are a great tool for targeting specific energy release paths. In this example, the detonation front cell size was significantly reduced by dissociating the oxygen a FEW nanoseconds ahead of the detonation front! I am delighted to share this Combustion and Flame study with you today: https://lnkd.in/ekpCVeMb This work demonstrates that very small changes in the chemical composition of the fresh gas ahead of a detonation can significantly alter the structure of the front. This work was realized in collaboration with my former group from Laboratory of Plasma Physics and Institut Pprime. #Detonation #PlasmaPhysics

Exciting developments in rocket propulsion research at our department! Take a look at the innovative work of our graduate researchers Benjamin Davis and Sai Phani Keerthan Ponduri, with Professor Jim Hermanson, in collaboration with international partners from ZARM and Kyushu University. Their poster, presented at our recent graduate showcase, demonstrates significant progress in understanding liquid oxygen droplet combustion in hydrogen under microgravity conditions. Key highlights of their research: - Numerical modeling of LOX droplet combustion in gaseous H2 - Complements microgravity experiments conducted at ZARM - Uses advanced EBI-DNS modeling coupled with liquid droplet phase simulation - Aims to improve understanding of flame structure, temperature, and combustion time This research has direct applications in rocket propulsion systems, where the LOX-H2 combination is widely used for its high performance. The team's findings on flame temperatures, stand-off distance, and heat transfer are pushing the boundaries of our understanding in this critical field. Great work!

🎉 Exciting News from the SoLid Experiment Team! 🎉 We're thrilled to share our first scientific results from the SoLid detector, analyzing antineutrinos from the BR2 reactor at SCK CEN. Our cutting-edge, highly detailed detector technology is pioneering advancements in our understanding of antineutrino behavior over very short distances. This analysis, based on a substantial dataset from both reactor-on and reactor-off periods, enhances our understanding of short-baseline neutrino oscillations. Check out our paper for a deep dive into our methods and findings: Search for Very-Short-Baseline Oscillations of Reactor Antineutrinos with the SoLid Detector: https://lnkd.in/eZ3jD5XV #NeutrinoPhysics #ParticlePhysics #SoLidExperiment #ScienceResearch

Four years to a flash! And what a momentous flash. This first plasma on the WHAM fusion experiment is the culmination of a massive collaboration from a team dedicate to making fusion a reality and to tackling climate change. My Realta Fusion co-founders Cary Forest, Jay Anderson and Oliver Schmitz cajoled, convinced and enlisted a fantastic team of scientific collaborators from University of Wisconsin-Madison, Commonwealth Fusion Systems (CFS), Massachusetts Institute of Technology, Princeton Plasma Physics Laboratory (PPPL) and more to work on the ARPA-E funded WHAM project. Along the way this project gave birth to Realta Fusion (which is now funding the ongoing experiment), and our mission is to take this major scientific advancement and engineer it into a working power plant. The speed at which the WHAM team were able to start-up this experiment after the delivery of the HTS magnets by CFS is a testament to the simplicity and robustness of the compact magnetic mirror concept. This simplicity will be a key factor in designing working and reliable fusion power plants.  And a note on timescales – something I had to learn when starting to work with plasma physicists. That flash is a very long time in plasma physics! It measured in milliseconds, but the plasma instabilities we are tackling happen in microseconds (a thousand times shorter). We can learn very quickly by running very short experiments and running many of them. We expect to run hundreds of experiments each week. WHAM is going to provide huge learning about how to optimize the mirror configuration and we’ll put those learning through rigorous peer review in scientific publications. A final shout-out to the Realta staff working in the WHAM team Doug Endrizzi, Jesse Viola, Elliot L. Claveau, Ph.D. and intern Timmy Bui who put in a huge effort alongside the UW team including many long and overnight shifts. Well done! Now let’s get more data…

🚀#mdpisymmetry Excited to share a newly published article with you. "Investigating Cathode Electrolyte Interphase Formation in NMC 811 Primary Particles through Advanced 4D-STEM ACOM Analysis" 🔸https://lnkd.in/gUjPq6n6 🔹Authors: Kevyn Gallegos-Moncayo et al. LRCS - Laboratoire de Réactivité et Chimie des Solides Centre national de la recherche scientifique Université de Picardie Jules Verne 🔸Abstract: This study focuses on NMC 811 (LiNi0.8Mn0.1Co0.1O2), a promising material for high-capacity batteries, and investigates the challenges associated with its use, specifically the formation of the cathode electrolyte interphase (CEI) layer due to chemical reactions. This layer is a consequence of the position of the Lowest Unoccupied Molecular Orbital (LUMO) energy level of NMC 811 that is close to the Highest Occupied Molecular Orbital (HOMO) level of liquid electrolytes, resulting in electrolyte oxidation and cathode surface alterations during charging... #cathode #electrolyte Physics Section of Symmetry
