The development of high temperature superconducting tape technology enabled the design compact fusion reactors, allowing faster in field. reduced size makes even more important evaluation neutron flux on all components and at every region, including magnet position, to assess lifetime materials their performances during operations. Compactness, however, introduces new technological challenges, considering space available for shielding consequently harsher radiation environment both...
In this work, a 3D FEM electro-thermal model of slotted core HTS cable, developed at the ENEA Frascati Superconductivity Laboratory (Italy) in collaboration with University Bologna and Eni S.p.A.

The also applied to compute normal zone propagation velocity. analysis finally provides critical information for design quench...
Abstract The management of hydrogen isotopes within a fusion reactor remains key design issue, with many constraints concerning tritium. power plant should be self-sufficient respect to its fuel, while the contamination components and releases outside primary system limited. There is need for versatile numerical tools assess tritium inventories losses, which will support relevant inform mitigation strategies. This work presents development, verification validation System-level Application...
Abstract Dissociation of active H + extrusion (−ΔH ) from K uptake in pea and maize root segments was attempted by substituting the incubation medium with lipophilic cations assumed to enter cell passive, non‐specific, permeation through lipid component plasmalemma. Among compounds tested, tributylbenzylammonium significantly stimulated −ΔH absence other monovalent medium. This effect much more evident when experiment carried out presence fusicoccin, which strongly stimulates proton cation...
Abstract We investigate the neutron damage expected in high-temperature superconducting tapes that will be employed compact fusion reactors. Monte Carlo simulations yield spectrum and fluence at magnet position, from which primary knock-on atom energy distributions can computed for each atomic species comprising superconductor. This information is then to characterize displacement cascades, terms of size morphology, through molecular dynamics simulations. The radiation environment compared...

Abstract Silicon carbide detectors represent an alternative to diamond for fast neutron detection in harsh environments, especially fusion plasmas. Previous studies on thin prototypes (either 10 μm or 100 thick) suggested that thicker active volumes might be better suited spectroscopy measurements, due the higher chance of retaining interaction products inside volume. Therefore, this work two 250 SiC are tested with alpha particles following same process conducted past thinner prototypes. A...

The state-of-the-art power supplies for superconducting magnets are bulky, expensive, and subjected to hundreds of kilowatts losses during operation producing significant reactive absorption harmonic distortion on the grid. Moreover, current is injected from room temperature 4 K coils through leads, which represent a major source heat load cooling system. Flux pumps contactless, compact supply systems able operate in nearly persistent mode with practically negligible losses. Although several...
Solid State Detectors (SSD) are crucial for fast neutron detection and spectroscopy in tokamaks due to their solid structure, neutron-gamma discrimination, magnetic field resistance.
