Dissimilar welds between austenitic stainless steels and EUROFER97 are unavoidable in the DEMO Oriented Neutron Source (DONES) Target Assembly (TA), particularly in the Backplate (BP), where 316L/316Ti piping joins EUROFER97 structural components exposed to extreme neutron flux, lithium velocity and thermal gradients that drive BP lifetime. This work assesses thin TIG (GTAW) butt welds in 1G...

One of the key characteristics of a neutron source is the energy spectrum of emitted neutrons. This allows, for example, inferences about the activation of various materials used to irradiate samples composed of different nuclear isotopes. In the case of fusion reactors, however, it is possible to determine basic parameters of the reactor fuel, i.e., the plasma, such as the Ti ion temperature...

Developing next-generation nuclear technologies, including fusion (ITER, DEMO) and Generation IV reactors, requires a precise understanding of material degradation under intense fast neutron fluxes. Degradations involve atomic displacement damage (dpa) and gas production (such as H or He) via transmutation, which trigger hardening, swelling, and embrittlement. Due to the limitations of fission...

By 2040, at least 100 tonnes of isotopically pure lithium-6 will be required to fabricate breeder blankets for STEP (Spherical Tokamak for Energy Production), the UK’s prototype fusion power plant. There is no currently established supply chain or large-scale lithium isotope enrichment plant to provide the needed quantities of lithium-6.

We propose a novel RF Timer based photoelectron emission spectrometer designed for the study of the energy and temporal characteristics of very low energy photoelectrons. In the near threshold regime, emitted electrons have kinetic energies from a few meV to several hundred meV, making their distributions highly sensitive to the work function, surface condition, electronic states near the...

Water plays a central role in the mechanical strength, durability, carbonation dynamics, and ion-driven degradation in cementitious systems. Yet the structure and dynamics of water within the poorly crystalline, nanoporous main binder phases of cement, especially in the newly emerging low-CO₂ cements, are difficult to characterize by conventional techniques. Neutron scattering offers unique...

The development of fusion energy systems requires advanced diagnostic techniques capable of characterizing radiation-induced defects in structural and functional materials with high sensitivity. Positron annihilation lifetime spectroscopy (PALS) is one of the most powerful methods for investigating vacancy-type defects, vacancy clusters, free-volume nanostructures, and irradiation-induced...
