Abstract

The European Spallation Source ESS is being constructed in Lund, Sweden, to be the world's brightest cold pulsed spallation neutron source. The facility uses a 2GeV proton beam hitting a target to produce neutrons. The neutrons are then thermalized in a moderator. Surrounding the moderator are several beam ports connected to neutron guides that transport the cold neutrons. Due to the long-pulse source nature of the ESS, neutron scattering instruments are significantly longer than at most existing facilities, with approximately half the instruments requiring neutron guides that are 150 meters long and only a few shorter than 50 meters. Therefore the shielding cost is dominated by the guide shielding. To fulfill the shielding requirement, a 'Common Shielding Project' has been initiated to deliver cost-effective and standardized solutions for several instruments. This includes both a consistent design of the shielding blocks, as well as a common approach to neutronics simulations., Comment: 4 pages, 8 figures, presented at the 14th International Conference on Radiation Shielding and 21st Topical Meeting of the Radiation Protection and Shielding Division, September 25 to 29, 2022 Seattle WA, USA, accepted for publication in the conference proceedings

Abstract

In this work we report on measurements of neutron absorption in supermirror coatings. The measurements were carried out using the SuperADAM instrument at the Institut Laue-Langevin and by measuring the gamma-ray production from m = 3 and m = 4 neutron supermirrors when illuminated by a beam of neutrons. The results provide a valuable validation for recent computational and theoretical work that can be used as input to Monte-Carlo radiation transport calculations for the design of the shielding of neutron scattering instruments.

Abstract

An overview is provided of the 15 neutron beam instruments making up the initial instrument suite of the European Spallation Source (ESS), and being made available to the neutron user community. The ESS neutron source consists of a high-power accelerator and target station, providing a unique long-pulse time structure of slow neutrons. The design considerations behind the time structure, moderator geometry and instrument layout are presented. The 15-instrument suite consists of two small-angle instruments, two reflectometers, an imaging beamline, two single-crystal diffractometers; one for macromolecular crystallography and one for magnetism, two powder diffractometers, and an engineering diffractometer, as well as an array of five inelastic instruments comprising two chopper spectrometers, an inverse-geometry single-crystal excitations spectrometer, an instrument for vibrational spectroscopy and a high-resolution backscattering spectrometer. The conceptual design, performance and scientific drivers of each of these instruments are described. All of the instruments are designed to provide breakthrough new scientific capability, not currently available at existing facilities, building on the inherent strengths of the ESS long-pulse neutron source of high flux, flexible resolution and large bandwidth. Each of them is predicted to provide world-leading performance at an accelerator power of 2 MW. This technical capability translates into a very broad range of scientific capabilities. The composition of the instrument suite has been chosen to maximise the breadth and depth of the scientific impact of the early years of the ESS, and provide a solid base for completion and further expansion of the facility.

Abstract

2 páginas, 1 tabla -- Póster presentado al Seminario sobre Biodiversidad Vegetal en el Sistema Agroforestal Atlántico, celebrado en Pontevedra (España) entre el 27 y el 28 de octubre de 2010., Tradicionalmente la caracterización de cultivares de vid se ha venido realizando mediante la descripción de sus características morfológicas y agronómicas, que –como es sabido- en muchos casos dependen en exceso de las condiciones ambientales. Así, la búsqueda de marcadores bioquímicomoleculares (DNA, enzimas,…) de utilidad para la caracterización y la clasificación de los cultivares de vid ha sido una constante. En este sentido, entre los compuestos metabólicos utilizados con éxito en quimiotaxonomía de la vid, destacan los de naturaleza fenólica, y entre ellos –y para las variedades tintas- los antocianos, responsables del color y alguna otra característica organoléptica de uvas y vinos. Pertenecen al grupo de los flavonoides y en las viníferas están presentes como formas monoglucosiladas de cinco antocianidinas (cianidina, delfinidina, petunidina, peonidina y malvidina) y sus correspondientes acetil, p-cumaroil y cafeoil derivados. Presentamos aquí la caracterización antociánica de seis cultivares tintos de vid cultivados en Galicia, el conocido como Tinta Oubiña y cinco de los que han adquirido mayor relevancia en nuestra Viticultura por su interés enológico: Mencía, Brancellao, Sousón, Merenzao y Mouratón., Agradecimientos a la Xunta de Galicia por la financiación del proyecto 07MRU016403PR; a la Excma.

Abstract

2 páginas, 2 tablas -- Póster presentado al Seminario sobre Biodiversidad Vegetal en el Sistema Agroforestal Atlántico, celebrado en Pontevedra (España) entre el 27 y el 28 de octubre de 2010., Los compuestos de naturaleza estilbénica han adquirido un considerable interés en los últimos tiempos, no sólo por sus propiedades como antioxidantes, que confieren efectos beneficiosos sobre la salud humana a los alimentos que los contienen, sino también por su papel en la defensa de las plantas frente a situaciones de estrés biótico y abiótico. En el caso concreto de la vid, estos compuestos han sido estudiados fundamentalmente en vinos tintos y por su interés en el campo de los alimentos funcionales, pero se sabe que muchos de ellos (resveratrol y derivados) actúan también como fitoalexinas frente al ataque de organismos patógenos. En este trabajo presentamos los resultados del análisis de estilbenos en mostos de la variedad Albariño y durante tres años consecutivos, con el objetivo de estudiar la posible relación entre el contenido en estos compuestos fenólicos y las condiciones ambientales, pudiéndose observar la existencia de diferencias significativas para dos de los estilbenos identificados, la trans-astringina y el trans-resveratrol., Excma.

Abstract

This article briefly describes the basic design of the ESS-Bilbao neutron target station as well as its expected neutronic performance. The baseline engineering design, associated ancillary systems, and plant layout for the facility is now complete. A rotating target composed of twenty beryllium plates has been selected as the best choice in terms of both neutron yield and engineering complexity. It will provide neutron beams with a source term of 1015 n s−1 resulting from the direct 9Be(p, xn) reaction using a 75 mA proton beam at 50 MeV. The design envisages a target station equipped with two fully optimized moderators capable of withstanding a proton-beam power of 112 kW. This design is flexible enough to accommodate future upgrades in final proton energy. The envisaged neutron-beam brightness will enable several applications, including the use of cold and thermal neutrons for condensed matter research as well as fast-neutron irradiation studies. We close by discussing the role that this facility may play once the European Spallation Source becomes operational in Lund, Sweden.
