Investigador - Física de partículas

Centro Nacional de Aceleradores
Sevilla

El CNA es un centro mixto Universidad de Sevilla, Junta de Andalucía y CSIC. Se trata de una Instalación Científico-Técnica Singular dedicada a la investigación interdisciplinar. Para ello se emplean 3 aceleradores de iones: un Tándem Van de Graaff de 3 MV, un Ciclotrón que proporciona protones de 18 MeV y deuterones de 9 MeV y un Tándem Cockcroft-Walton de 1 MV, utilizado como espectrómetro de masas. La aplicación de estos 3 aceleradores cubre campos tan variados como ciencias de materiales y ambientales, física nuclear y de partículas, instrumentación, tratamiento de imágenes médicas, investigación biomédica e imagen molecular, entre otras.

Description:

The proposed research project is included in a network within the FP7 Marie Curie Initial Training Network  scheme. It is focused on the optimization of the 10Be detection at CNA, which is actually in a primary stage. The work should include an intense investigation on the physical processes involved in the 10Be detection by AMS, the search of the optimum conditions of the existing system for this and the design of modifications in order to increase sensitivity and efficiency. In order to do this, the study of the current system should lead to the test of a new ionization chamber for isotope detection and the possibilities of a second analyzing magnet. The influence of these improvements on the measurement of other radionuclides currently detected at CNA should also be considered. Also, the injection of other ions in the accelerator instead of BeO must be studied as a way of reducing B contamination directly in the ion source. The project will be developed at the National Center of Accelerators (CNA) at Sevilla (Spain), where two AMS facilities are available.
