Neutron assay has been a critical (no pun intended) part of radiometric measurement ever since some of the first nuclear experiments in the 20th century. At Sellafield we use Neutron detectors in installed assay suites, in Health Physics instrumentation and in portable characterisation toolkits in order to understand our nuclear material inventories and keep the site safe. https://lnkd.in/gHsYnZ2V #Sellafield #characterisation #nuclearphysics #nucleardecommissioning

Defence and Security Accelerator and Dstl are doing some sort of magic; if you think you can help in the latest request for Market Exploration, get involved! Jedis, Magicians, and Scientists should consider getting involved. #Innovation #science #defence

I'm pleased to share that our paper investigating the microscopic structure of molten FLiBe has been published in PRX Energy. FLiBe has gained prominence for its usefulness in energy applications, particularly in advanced nuclear reactors. We measured FLiBe using neutron and X-ray scattering techniques to compare with predictions from machine-learning-enhanced molecular dynamic simulations. In the future, these types of simulations will aid in predicting and controlling how the physical properties of the salt might change during operation. https://lnkd.in/eqqUAdji

I'm glad to announce that we are back in the fields! Campaign to Measure Cosmic Ray Neutrons The ENPAI research team, part of the Advanced Nuclear Technology (ANT) group at UPC Barcelona, is proud to announce a new campaign to measure neutrons generated by cosmic rays! This innovative project utilizes the newly developed HENSA++ spectrometer, built by IFIC(CSIC, Valencia) and ENPAI (UPC). The campaign is a collaboration with the IAXO dark matter experiment team at the University of Zaragoza. Key Points: Two-week campaign to measure background neutron levels for the IAXO dark matter experiment. HENSA++ spectrometer: State-of-the-art neutron detection system for high-efficiency measurements. Two-phase approach: Outdoor measurements (started today!) to avoid interference, followed by indoor measurements to study wall influence. Goal: Deeper understanding of cosmic ray neutrons and aiding IAXO experiment design and sensitivity. https://ant.upc.edu #darkmatter #cosmicrays #neutrons #research #barcelona #UPC #IAXO #HENSA #ANT

Defence and Security Accelerator is reaching out to industry and academia via a new Market Exploration to get an understanding of the levels of knowledge and skills in the areas of Nuclear Quadrupole Resonance and Electron Spin Resonance for the purpose of detecting solid and liquid explosives and drugs.    We are interested in what currently exists (or could exist with more funding) in these fields, so your input will get in front of key UK and international government stakeholders as well as helping to shape future funding. 

🥽 Nuclear magnetic resonance (NMR) is one of the most widely used techniques to elucidate the structure of macromolecules. 🧬 Learn more about it with this carousel. 👁️ 📌 https://oligofastx.com/ #fundedbyCDTI

I am thrilled to announce that our paper "Non-modal stability analysis of magneto-hydrodynamic flow in a single pipe" has been published by the Fundamental Plasma Physics journal. A complete understanding of the stability of fluid flows under varying magnetic fields is imperative for achieving control of plasma and operating fluids in the blankets of future nuclear fusion reactors.  This study investigates the influence of varying magnetic profiles on the flow regime of a generic fluid, which is representative of both thermonuclear plasma and conductive fluids. Firstly, the classic modal stability technique is employed to study asymptotical stability. Then, non-modal stability analysis is applied to study the system's response for a finite time immediately after a perturbation. If you want to know more, here is the full article. #NuclearFusion #PlasmaPhysics #Magnetohydrodynamics #NonModalStabilityAnalysis

The principle of NMR usually involves three sequential steps: 1.The alignment (polarization) of the magnetic nuclear spins in an applied, constant magnetic field B0. 2.The perturbation of this alignment of the nuclear spins by a weak oscillating magnetic field, usually referred to as a radio-frequency (RF) pulse. 3.Detection and analysis of the electromagnetic waves emitted by the nuclei of the sample as a result of this perturbation. #chemist
