El acelerador de partículas enano es capaz de acelerar los electrones a una velocidad diez veces mayor que la que consigue la tecnología convencional.

Científicos de Estados Unidos lograron crear un chip-láser que acelera los electrones a una velocidad diez veces mayor de como lo consigue la tecnología convencional.

Las dimensiones del Gran Colisionador de Hadrones (LHC, por sus siglas en inglés), el acelerador de partículas más grande y potente del mundo, son extraordinarias.

El acelerador se encuentra en un túnel en forma de circunferencia de 27 kilómetros, enterrado bajo la frontera franco-suiza. En él se llevan a cabo experimentos que están ayudando a descifrar los misterios de la física y a entender los orígenes del universo.

¿Podría todo eso reducirse al tamaño de un grano de arroz? Científicos del Centro del Acelerador Lineal de Standford (SLAC, por sus siglas en inglés) y de la Universidad de Stanford, en EE.UU., han demostrado que sí es posible., según el portal científico Tendencias21.

Los investigadores lograron insertar en un chip de cristal nanoestructurado de unos 3 milímetros un láser capaz de acelerar los electrones a una velocidad diez veces mayor que la que consigue la tecnología convencional.

En su máximo potencial, el nuevo acelerador puede alcanzar en solo 30 metros el mismo poder de aceleración que alcanza el acelerador lineal de SLAC en dos kilómetros y emitir un millón más de pulsos de electrones por segundo.

Según los autores del experimento, fabricar este chip es fácil y barato, por lo que, en su opinión, el logro sienta las bases para las nuevas generaciones de “aceleradores de escritorio”, como han sido denominados por los investigadores.

“Todavía tenemos varios desafíos que superar antes de que esta tecnología llegue a ser práctica en el mundo real, pero podría ayudar a reducir sustancialmente el tamaño y el coste de los futuros colisionadores de partículas de alta energía para explorar el mundo de las partículas y las fuerzas fundamentales”, explica Joel England, físico del SLAC que dirigió los experimentos.

Además, este nuevo acelerador podría utilizarse para obtener fuentes de rayos X portátiles para mejorar la seguridad y atención médica y proporcionar imágenes médicas más económicas para hospitales y laboratorios, según sus creadores.

    To be a core point guard, garage along with three split the difference is he is the team sponsor and organizer. In additional words, he can't be similar to novak on the perimeter around anticipating kd shoes someone else to provide him the ball. We take novak into a comparison, everything also - reference counted for all of us each a 3-pointer helps objects, and to time period, after statistics, novak found this year hit 3-pointers, 149, 146 can be a teammate's pass and strike; Three-point shots hit the second more this season Ryan - Anderson is not any exception, he hit curry shoes within 213, has 206 will depend on your friend's passing.


    The garage He the many 3-pointer this season, you'll find 105 of 3 is just not sending (272), in other words, is to create prospects, nasty sto vote. This trick within the team's star, such since flow of harden, vladimir radmanovic, kobe Bryant, Robert, but often because an individual errs, physical strength use, to the number of that time period few, and the hit ratio is not high. But obviously is usually an exception in the Treasury, his three-point shot 105 times isn't assists quantity highest with alliance,stephen curry shoes even better in comparison with lebron James thrown in to more all 3-pointers, and also the shooting is in some sort of league all five these kinds of not assists free-throw shooting players from the fifth (41. 8%), the two quality and quantity. Used together, the three points to be able to thrown into space just isn't an easy thing, will need to have the forty percent three-point shots should create his own shots, this how tired! The most precious is, no make any difference when and where, and how to make moves, garage has a top percentage. It is no wonder that this manager of the players when Bob myers not too long ago told the Associated Mass media said: "as long as it's garage, to obtain the ball is reasonable. inch.
