Abstract

Un bucle de conducción tiene una sección transversal gruesa y se energiza por una única fuente de voltaje con la capacidad de producir extremadamente altas. Los segmentos anti-paralelos del bucle se llevan en cercana proximidad entre sí y a los segmentos sin par en este bucle les se han dado la forma para formar colectivamente un campo B0 homogéneo. Las fuentes de voltaje derivan la corriente desde un punto del bucle grueso hasta otro, tal que la redistribución resultante de corriente dentro del bucle grueso permite que establezca en forma simultánea los campos de gradiente requeridos y/o los campos de calce requeridos además de su campo B0.
