Abstract

Métodos para mantener un perfil de haz específico de un haz de rayos X extraido de un objetivo de rayos X sobre un gran intervalo de angulos de extracción con relación al objetivo. Se genera un haz de electrones y se dirige hacia un objetivo en un ángulo de incidencia con respecto al objetivo, con el haz de electrones que forma un punto focal que corresponde a la sección transversal del haz de electrones. Al menos uno de un tamaño, forma y orientación de la sección transversal del haz de electrones se varía dinámicamente conforme se varía el ángulo de extracción, y se colima el haz de rayos X extraido. La variación dinámica del tamaño, forma u orientación de la sección transversal del haz de electrones se puede realizar usando bobinas correctoas de astigmatismo y enfoque.
