Abstract

SE DESCRIBE UN APARATO MEJORADO PARA GENERAR UNA REGION DE RESONANCIA CICLOTRONICA DEL ELECTRON (ECR) UNIFORME EN UNA REGION DE PLASMA (16) DE UNA CAMARA (15). EL APARATO UTILIZA MODOS MAS ALTOS DE CUSPIDES DE CAMPOS ELECTRICOS (16B) QUE SON ESENCIALMENTE PERPENDICULARES A LAS CUSPIDES DE CAMPO MAGNETICO (16A) DE FORMA CONTROLADA PARA PRODUCIR LA ECR. LOS MODOS SON OPTIMOS EN LA REGION ECR.
