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).

Beamtime periods 2012

Beamtime request service
CMAM has posted the information about beamtime periods and deadlines for the next year 2012.

For more information about this, you can visit our beamtime section. Remember, if you wish to send a beamtime proposal, you must use our beamtime request service. All the information about beamtime periods and deadline for year 2012 has been updated here too.

 
Open days at CMAM

One more year, the Science week is going to take place, which is the biggest science and technology social media event in Spain.

"Ministerio de Ciencia e Innovación", being aware of the need to create a social enviroment that is geared towards science and innovation, supports through FECYT the activities that are organized throughout Spain in the Science Week.

Museums, universities, research centers, technology parks and companies are going to organize exhibitions, courses, tours, workshops, roundtables,
tours and conferences, bringing the general public their daily work.

CMAM is going to participate once more in the "XI Semana de la Ciencia", organizing the activity "Los aceleradores de iones como Instrumento de Análisis Químico", joinig in the celebration of the International year of Chemistry.

The activities are two open days to visit the Accelerator of CMAM in November 10th and 17th 2011, 10-13:00 or 15:00-18:00

If you are interested in this visit, you can make a book on: 91 497 3219 or email: visitas.cmam@uam.es

For more information about this event, you can visit the website about the activities of the Science week.
