Abstract

SE DESCRIBE UN SELECTOR DE MASA PARA SEPARAR PARTICULAS EN UN HAZ DE PARTICULAS SEGUN SU MASA. EL SELECTOR TIENE UN PAR DE PRIMEROS ELECTRODOS (12, 14) QUE DEFINEN UNA PRIMERA TRAYECTORIA ALARGADA (16) PARA EL PASO DE UN HAZ ENFOCADO DE PARTICULAS. UN PAR DE SEGUNDOS ELECTRODOS (24, 26) ESTAN SEPARADOS DEL PAR DE PRIMEROS ELECTRODOS (12, 14) Y DEFINEN UNA SEGUNDA TRAYECTORIA ALARGADA (28) PARA PARTICULAS SEPARADAS. LA PRIMERA Y SEGUNDA TRAYECTORIAS (16, 28) SON PARALELAS. SE APLICA UN PRIMER IMPULSO DE CORRIENTE A TRAVES DE LOS PRIMEROS ELECTRODOS (12, 14), DE FORMA QUE LAS PARTICULAS EN UNA PARTE DEL HAZ QUE ESTA EN LA PRIMERA TRAYECTORIA (16) SE ACELEREN TRANSVERSALMENTE RESPECTO A SU DIRECCION DE MOVIMIENTO A LO LARGO DE DICHA PRIMERA TRAYECTORIA HACIA DICHA SEGUNDA TRAYECTORIA. UN SEGUNDO IMPULSO DE CORRIENTE SE APLICA A TRAVES DE LOS SEGUNDOS ELECTRODOS (24, 26), DE FORMA QUE LAS PARTICULAS QUE HAN SIDO ACELERADAS POR DICHO PRIMER IMPULSO DE CORRIENTE Y QUE HAN ENTRADO EN DICHA SEGUNDATRAYECTORIA (28) SEAN DESACELERADAS TRANSVERSALMENTE RESPECTO A SU DIRECCION DE MOVIMIENTO A LO LARGO DE DICHA SEGUNDA TRAYECTORIA.
