The charged particle accelerators were originally developed for pursuing research in frontier areas of physics. They are now being used not only for basic research in science, but also in a variety of applications of great relevance to the society. The charged particle accelerators are employed in health care, industry, agriculture, national security, environment, archaeology and cultural heritage related programmes. An overview of the charged particle accelerators; the ion and the electron types, the national and international scenario and the application potential of these accelerators in various programmes is provided in this article.

Particle accelerators for colombia AbstractThe foundations and historical development of particle accelerators are presented in this article, detailing on the synchrotron, the principle of phase stability, synchrotron principle. Storage rings, synchrotrons at constant magnetic field, are introduced. For the electron synchrotron, synchrotron radiation is presented and how to exploit it with the use of undulators as X-ray sources. Radiation properties of undulators are highlighted for applications in science and industry. This motivates to present a proposal for a synchrotron radiation center for Colombia with an electron synchrotron operating as storage ring and undulators as X-ray emitters, for multiple applications for research, development and innovation in science, technology and industry.Key words: Particle accelerators, synchrotrons, synchrotron radiation, undulators. Ciencias físicas IntroducciónEn el mundo de los aceleradores de partículas de hoy existen aproximadamente unos 15000 aceleradores. De ellos la gran mayoría son instalaciones comerciales que se encuentran en hospitales y están dedicadas exclusivamente a la medicina nuclear, para diagnóstico, terapia y para la producción de isótopos radioactivos de múltiples aplicaciones en la medicina. Hay también aceleradores de aplicación en la industria en los países desarrollados y, claro está, también los institutos de investigación y laboratorios en las diversas ciencias naturales cuentan con sus propios aceleradores, principalmente en la física nuclear y en la física de altas energías, donde se destacan las mayores instalaciones del mundo como el Laboratorio CERN 1 en Ginebra, Suiza.

“…In the past years, nanostructures have attracted intense research interest due to their new properties not seen in bulk counterparts [1][2][3]. Ion irradiation is a powerful tool to tune the properties of materials [4][5][6][7] for a wide range of applications [8][9][10][11][12]. In many cases, ion implantation is also the method of choice for doping nanostructures, since this method is not constrained by thermal equilibrium [4,13,14].…”

Ion beam processing of surfaces is well known to lead to sputtering, which conventionally is associated only with erosion of atoms from the material. We show here, by combination of experiments and a newly developed Monte Carlo algorithm, that in the case of nanoparticles in a regular twodimensional array on surfaces, the redeposition of sputtered atoms may play a significant role on the system development. The simulations are directly compared to in situ experiments obtained using a dual focused Ga + ion beam system and high resolution scanning electron microscopy, and explain the size evolution by a combination of sputtering and redeposition of sputtered material on neighboring particles. The effect is found to be dependent on the size of the nanoparticles: if the nanoparticle size is comparable to the ion range, the reposition is negligible. For larger nanoparticles the redeposition becomes significant and is able to compensate up to 20% of the sputtered material, effectively reducing the process of sputtering. The redeposition may even lead to significant growth: this was seen for the nanoparticles with the sizes much smaller than the ion range. Furthermore, the algorithm shows that significant redeposition is possible when the large size neighboring nanoparticles are present.
