Overview of the JET results
Since the installation of an ITER-like wall, the JET programme has focused on the consolidation of ITER design choices and the preparation for ITER operation, with a specific emphasis given to the bulk tungsten melt experiment, which has been crucial for the final decision on the material choice for the day-one tungsten divertor in ITER. Integrated scenarios have been progressed with the re-establishment of long-pulse, high-confinement H-modes by optimizing the magnetic configuration and the use of ICRH to avoid tungsten impurity accumulation. Stationary discharges with detached divertor conditions and small edge localized modes have been demonstrated by nitrogen seeding. The differences in…
Síndrome de Mc Cune Albright: a propósito de un caso
Se presenta el caso de un niño varón de 6 años que tras presentar una clínica de claudicación a la marcha progresiva durante 3 meses, sin antecedente de traumatismo, es diagnosticado de fractura patológica de cuello femoral izquierdo en el contexto de un síndrome de Mc Cune Albright. Se realiza también un análisis del diagnóstico, seguimiento y las opciones terapéuticas de esta rara enfermedad. A case of a boy of 6 years old after presenting a progress claudicating over 3 months, no history of trauma, is diagnosed with pathological fracture of left femoral neck in the context of Mc Cune Albright syndrome. An analysis of the diagnosis, monitoring and treatment options of this rare disease is…
Overview of the JET results with the ITER-like wall
Following the completion in May 2011 of the shutdown for the installation of the beryllium wall and the tungsten divertor, the first set of JET campaigns have addressed the investigation of the retention properties and the development of operational scenarios with the new plasma-facing materials. The large reduction in the carbon content (more than a factor ten) led to a much lower Zeff (1.2-1.4) during L- and H-mode plasmas, and radiation during the burn-through phase of the plasma initiation with the consequence that breakdown failures are almost absent. Gas balance experiments have shown that the fuel retention rate with the new wall is substantially reduced with respect to the C wall. T…
