betatron


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

be·ta·tron

(bā'tă-tron),
A circular electron accelerator that is a source of either high energy electrons or x-rays.

betatron

A cyclotron which accelerates electrons via a pulsating magnetic field, imparting up to 20 MeV of energy. The first medical betatron was opened in the 1950s, but was limited by the low attainable strength of the magnetic field and the size of the magnetic core.

En la Universidad de Illinois, Urbana, en 1940 Donald Kerst perfecciono la idea del transformador de rayo y su diseno, el betatron, constituyo un muy exitoso invento para acelerar electrones hasta energias de cientos de MeV, que acelerador que se mantuvo vigente hasta finales de la decada de 1970 como el acelerador para aplicaciones medicas en terapia del cancer [Ke40], [Ke41], [Ke42].
Si el rango de energias de un acelerador es adecuado para cierta area de investigacion que no requiere las mas altas energias o para aplicaciones en la industria, o en la medicina, el acelerador se mantiene, mientras su operacion sea razonable hasta ser superado en los demas aspectos tecnologicos, o de costos de operacion, como en el caso ya mencionado del betatron.
