Experimental modeling of fine sediment routing: SEDMIX device with thrusters
Giovanni De Cesare, Azin Amini, Montana Marshall
Reservoir sedimentation is a key challenge for storage sustainability because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. A preliminary EPFL study proposed and studied an innovative device (called SEDM ...
CRC Press/Balkema2023Using continuous electrical conductivity measurements to derive major solute concentrations in karst systems
Hydrochemical data of karst springs provide valuable insights into the internal hydrodynamical functioning of karst systems and support model structure identification. However, the collection of high-frequency time series of major solute species is limited ...

2023Status of SPIDER beam source after the first 3.5 years of operation
SPIDER is the negative ion source testbed for ITER neutral beam injector. It is currently the largest negative ion source ever built, equipped with a 100 keV accelerator, aiming at producing a negative ion beam with an extracted current density in hydrogen ...
2023Design of an intake and a thruster for an atmosphere-breathing electric propulsion system
Francesco Romano, Thomas Binderup Jensen
Challenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that finally defines the mission's lifetime, unless a way to compensate for it is provided. This environment is named ...
2022Negative ion density in the ion source SPIDER in Cs free conditions
The SPIDER experiment, operated at the Neutral Beam Test Facility of Consorzio RFX, Padua, hosts the prototype of the H-/D- ion source for the ITER neutral beam injectors. The maximization of the ion current extracted from the source and the minimization o ...
2022A 1.5D fluid-Monte Carlo model of a hydrogen helicon plasma
Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Riccardo Agnello
Helicon plasma sources operating with hydrogen or deuterium might be attractive for fusion applications due to their higher power efficiency compared to inductive radiofrequency plasma sources. In recent years, the resonant antenna ion device (RAID) has be ...
IOP Publishing Ltd2022First operations with caesium of the negative ion source SPIDER
Riccardo Agnello, Michele Fadone, Alberto Ferro
The negative-ion based neutral beam injector for heating and current drive of the ITER plasma (ITER HNB) is under development, at present focusing on the optimization of the full-scale plasma source in the SPIDER test stand. The production of H- or D- ions ...
