Turbulence and particle energization in twisted flux ropes in solar-wind conditions
Oreste Pezzi, Domenico Trotta, Simone Benella +6
Context. The mechanisms regulating the transport and energization of charged particles in space and astrophysical plasmas are still debated. Plasma turbulence is known to be a powe…
Divertor shaping with neutral baffling as a solution to the tokamak power exhaust challenge
K. Verhaegh, J. R. Harrison, D. Moulton +20
Exhausting power from the hot fusion core to the plasma-facing components is one of the biggest challenges in fusion energy. The MAST Upgrade tokamak uniquely integrates strong con…
The HIBEAM Instrument at the European Spallation Source
V. Santoro, D. Milstead, P. Fierlinger +61
The European Spallation Source (ESS) will be the world's brightest neutron source and will open a new intensity frontier in particle physics. The HIBEAM collaboration aims to explo…
Direct current measurements of the SPIDER beam: a comparison to existing beam diagnostics
A. Shepherd, T. Patton, A. Pimazzoni +5
For negative ion beam sources there are several methods of measuring the accelerated beam current, most commonly electrical measurements at the power supply and calorimetric measur…
Three-dimensional modelling of the shock-turbulence interaction
Domenico Trotta, Oreste Pezzi, David Burgess +12
The complex interaction between shocks and plasma turbulence is extremely important to address crucial features of energy conversion in a broad range of astrophysical systems. We s…
Galactic cosmic ray transport in the absence of resonant scattering
O. Pezzi, P. Blasi
Galactic cosmic ray transport relies on the existence of turbulence on scales comparable with the gyration radius of the particles and with wavenumber vector oriented along the loc…
Integration studies of RF solid-state generators in the electrical system of NBTF experiments and ITER HNB
R. Casagrande, A. Maistrello, M. Recchia +5
SPIDER operation, started in 2018, pointed out performance-limiting issues caused by the technology employed in RF generators, based on tetrode free-running oscillators. One of the…
Spider Ion Source and Extraction Power Supplies -- An update of the design after four years of operation
A. Shepherd, M. Bigi, R. Casagrande +6
SPIDER, the ion source prototype for ITER neutral beam injectors, has been in operation since 2018. The experiment includes a system of Ion Source and Extraction Power Supplies (IS…
Partial Discharges detection in 1 MV power supplies in MITICA experiment, the ITER Heating Neutral Beam Injector prototype
Marco Boldrin, Mattia Dan, Vanni Toigo +11
MITICA (Megavolt ITER Injector & Concept Advancement), the full scale prototype of ITER Heating Neutral Beam, is under realization at the Neutral Beam Test Facility (Padova, Italy)…
Overview on electrical issues faced during the SPIDER experimental campaigns
Alberto Maistrello, Matteo Agostini, Marco Bigi +39
SPIDER is the full-scale prototype of the ion source of the ITER Heating Neutral Beam Injector, where negative ions of Hydrogen or Deuterium are produced by a RF generated plasma a…
Lessons learned after three years of SPIDER operation and the first MITICA integrated tests
D. Marcuzzi, V. Toigo, M. Boldrin +139
ITER envisages the use of two heating neutral beam injectors plus an optional one as part of the auxiliary heating and current drive system. The 16.5 MW expected neutral beam power…
Does Turbulence along the Coronal Current Sheet Drive Ion Cyclotron Waves?
Daniele Telloni, Gary P. Zank, Laxman Adhikari +32
Evidence for the presence of ion cyclotron waves, driven by turbulence, at the boundaries of the current sheet is reported in this paper. By exploiting the full potential of the jo…
Helios 2 observations of solar wind turbulence decay in the inner heliosphere
Luca Sorriso-Valvo, Raffaele Marino, Foldes Raffaello +5
The linear scaling of the mixed third-order moment of the magnetohydrodynamic fluctuations is used to estimate the energy transfer rate of the turbulent cascade in the expanding so…
