Optimizing beam-ion confinement in ITER by adjusting the toroidal phase of the 3D magnetic fields applied for ELM control
(IOP Publishing, 2021-03)
The confinement of neutral beam injection (NBI) particles in the presence of n = 3 resonant magnetic perturbations (RMPs) in 15 MA ITER DT plasmas has been studied using full orbit ASCOT simulations. Realistic NBI distribution ...

Coils and power supplies design for the SMART tokamak
(Elsevier Ltd, 2021)
A new spherical tokamak, the SMall Aspect Ratio Tokamak (SMART), is currently being designed at the University of Seville. The goal of the machine is to achieve a toroidal field of 1 T, a plasma current of 500 kA and a ...

Energetic particle acceleration and transport by Alfven/acoustic waves in tokamak-like Solar flares
(Cambridge University Press, 2011)
Alfv´en/acoustic waves are ubiquitous in astrophysical as well as in laboratory plasmas. Their interplay with energetic ions is of crucial importance to understanding the energy and particle exchange in astrophysical ...

Energy fluctuations in a randomly driven granular fluid
(Taylor & Francis, 2009)
We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is derived and the hydrodynamic eigenvalues are ...

Critical-point symmetries in Boson-Fermion systems: The case of shape transitions in odd nuclei in a multiorbit model
(American Physical Review, 2007-02-05)
We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model [E(5/12)] to describe odd nuclei at the critical point in the transition from the spherical to γ-unstable behavior. In ...

Challenges in the extrapolation from DD to DT plasmas: experimental analysis and theory based predictions for JET-DT
(IOP Publishing, 2017-01)
A strong modelling program has been started in support of the future JET-DT campaign with the aim of guiding experiments in deuterium (D) towards maximizing fusion energy production in Deuterium–Tritium (DT). Some of the ...

Scintillator ageing of the T2K near detectors from 2010 to 2021
(Institute of Physics Publishing, 2022)
The T2K experiment widely uses plastic scintillator as a target for neutrino interactions and an active medium for the measurement of charged particles produced in neutrino interactions at its near detector complex. Over ...

Neutron capture cross section of unstable 63Ni: implications for stellar nucleosynthesis
(American Physical Society, 2013-01-08)
The 63Ni(n,γ) cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were ...

Quadrupole moments and E2 transitions in the O(6) limit of the IBM
(Elsevier, 1988)
Quadrupole moments and E2 transitions in the O(6) limit of the interacting boson model are studied within a formalism based on the intrinsic frame. We show that the values of these quantities for both ground- and β-bands ...
