Open day in Physics Degree

CMAM has participated in the Open day in Physics Degree for high school students organized on 20th December, 2011 by the Faculty of Sciences.


As a part of day, which included visits to different deparments of UAM Physics, 40 students who have been accompained by David Martín y Marero and Alessandro Zucchiatti, have visited the accelerator and have been able to carry out a small illustrative experiment of the PIXE tecnique.

 
CMAM in the Treasury Quimbaya project

Treasury quimbaya pieceCMAM has participated in an international project of "Consejo Superior de Investigaciones Científicas" (CSIC) in collaboration with the "Museo de América de Madrid", that has estudied the latest developments in observational techniques and non-destructive analysis of a set of pre-Columbian metallurgy pieces.

This project tries to know the manufacture process, assembly and use of gold pieces from Costa Rica and the archeologycal site known as Treasury Quimbaya from Colombia. The pieces have been moved from Museum to our laboratory, where has been analized with ion beams generated in the accelerator of CMAM.

For more information about the news you can visit the CSIC website.

New Thesis at CMAM about "Ion beam damage by electronic excitation with swift heavy ions in lithium niobate: mechanisms and nanostructuring for photonic applications"

Defended by Miguel Crespillo Almenara at the Faculty of Sciences of the Universidad Autónoma de Madrid on 12th December 2011.


during the presentation The aim of the Thesis has been to study the origin, main features and potential applications of the damage produced by high density electronic excitation under high energy heavy ion irradiation (i.e. swift heavy ions). From the fundamental point of view it discusses the different mechanisms responsible for the observed damage. This has been addressed under some specific modelling and by studying the thermal stability of the electronic damage. The unique nanostructuring capabilities offered by the damaged ion tracks (nanometer diameter and microns length) has been exploited to study, in LiNbO3, the fabrication of special nanopores structures and thick (up to ~40 µm) optical waveguides based on nanostructured effective optical medium obtained at ultralow fluence (~1011 at/cm2).

This research has been carried out at the Centro de Micro-Análisis de Materiales (CMAM) of the UAM where most of the ion irradiations (with ion energies up to 50 MeV) have been performed. Some very high energy irradiations (~1000 MeV) have been performed at GANIL (Caen, France) and GSI (Darmstadt, Germany).
