Effect of elastic transfer in sub-barrier fusion between similar nuclei
(American Physical Society, 1987)
We study the effect of the elastic transfer process on sub-barrier fusion reactions between similar nuclei. The coupling to the elastic transfer channel is described in terms of a parity dependent potential, directly ...

Simultaneous measurement of neutron-induced capture and fission reactions at CERN
(Springer Verlag, 2012)
The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the γ-ray ...

Deposition of impurity metals during campaigns with the JET ITER-like Wall
(Elsevier, 2019-05-19)
Post mortem analysis shows that mid and high atomic number metallic impurities are present in deposits on JET plasma facing components with the highest amount of Ni and W, and therefore the largest sink, being found at the ...

Population modelling of the He II energy levels in tokamak plasmas: I. Collisional excitation model
(IOP Publishing, 2019-02-28)
Helium is widely used as a fuel or minority gas in laboratory fusion experiments, and will be present as ash in DT thermonuclear plasmas. It is therefore essential to have a good understanding of its atomic physics. To ...

Comment on “Pairing interaction and Galilei invariance”
(American Physical Society, 1999)
A recent article by Dussel, Sofia, and Tonina studies the relation between Galilei invariance and dipole energy weighted sum rule (EWSR). The authors find that the pairing interaction, which is neither Galilei nor Lorentz ...

An instanton picture O.P.E. (A2) condensate?
(Elsevier, 2003)
Gluon two- and three-point Green Functions computed in Landau gauge from the lattice show the existence of power corrections to the purely perturbative expressions, that can be explained through an Operator Product Expansion ...

Velocity-space resolved measurements of fast-ion losses due to magnetohydrodynamic instabilities in the ASDEX Upgrade tokamak.
(2018-12-17)
The confinement of suprathermal ions in magnetically confined fusion plasmas is essential to ensure a good fusion performance. Auxiliary heating systems - and fusion reactions themselves - create fast-ion populations, which ...

Dynamical behavior of a one-dimensional Ising model submitted to continuous heating and cooling processes
(American Institute of Physics Publising LLC, 1994)
The evolution of a one-dimensional Ising model with Glauber dynamics and an extrinsic energy barrier, submitted to continuous cooling and heating processes, is studied. The model is shown to exhibit many of the properties ...

L to H mode transition: parametric dependencies of the temperature threshold
(IOP Publishing, 2015-07)
The L to H mode transition occurs at a critical power which depends on various parameters, such as the magnetic field, the density, etc. Experimental evidence on various tokamaks (JET, ASDEX-Upgrade, DIII-D, Alcator C-Mod) ...
