Studying radon exhalation rates variability from phosphogypsum piles in the SW of Spain
(ELSEVIER SCIENCE BV, 2014)
Nearly 1.0×108 tonnes of phosphogypsum were accumulated during last 50 years on a 1200ha disposal site near Huelva town (SW of Spain). Previous measurements of exhalation rates offered very variable values, in such a way ...

Quodon Current in Tungsten and Consequences for Tokamak Fusion Reactors
(WILEY-V C H VERLAG GMBH, 2024)
Tokamak fusion reactors produce energetic He ions that penetrate surfaces less than 20 μm and neutrons that spread throughout the reactor. Experiments with similar swift He ions in heavy metals show that the vibronic ...

On the proximity between the wave dynamics of the integrable focusing nonlinear Schrödinger equation and its non-integrable generalizations
(Elsevier, 2024-07)
The question of whether features and behaviors that are characteristic to completely integrable systems persist in the transition to non-integrable settings is a central one in the field of nonlinear dispersive equations. ...

Surface modification of ITER-like mirrors after one hundred cleaning cycles using radio-frequency plasma
(Elsevier, 2023-08)
In ITER, the metallic first mirrors (FMs) will undergo erosion due to their proximity to the fusion plasma and deposition of materials originated from the first walls (mainly beryllium). In-situ plasma cleaning is a promising ...
