Abstract

APARATO DE RADIOGRAFIA NEUTRONICA Y APARATO PARA GENERAR UN HAZ DE NEUTRONES PARA DICHA RADIOGRAFIA. HAY UN COLIMADOR CONVERGENTE DE MATERIAL MODERADOR UNIDO COAXIALMENTE A UN COLIMADOR DIVERGENTE HECHO DE MATERIAL ABSORBENTE DE NEUTRONES. UNA ABERTURA ESTA FORMADA ENTRE LOS COLIMADORES. EL COLIMADOR DIVERGENTE DEFINE SUSTANCIALMENTE UN HAZ DE NEUTRONES. UN PLANO DE FORMACION DE IMAGEN ESTA DISPUESTO DENTRO DEL HAZ DE NEUTRONES. EL COLIMADOR CONVERGENTE TIENE UNA BASE QUE DEFINE UN PLANO FUENTE. RADIOISOTOPOS EMISORES DE NEUTRONES, QUE SON UNA FUENTE DE NEUTRONES, ESTAN SITUADOS SIMETRICAMENTE ALREDEDOR DEL PLANO FUENTE. MATERIAL MODERADOR DE NEUTRONES ESTA SITUADO ENTRE LAS FUENTES DE NEUTRONES Y LA ABERTURA. LA FORMA CONVERGENTE-DIVERGENTE DE LOS COLIMADORES ESTA DISEÑADA PARA EXPONER TODO EL PLANO FUENTE PARA LA IRRADIACION OPTIMA Y UNIFORME DEL PLANO DE FORMACION DE IMAGEN POR NEUTRONES TERMICOS. APLICACION AL ENSAYO NO DESTRUCTIVO DE MATERIALES.
