Abstract

SE PROVEEN ELEMENTOS (45, 45'', 45'''', 61 Y 62) DE TRANSICION MAGNETIZADOS ENTRE LOS ELEMENTOS (31, 47, 47'' Y 47'''') QUE DEFINEN LA CAVIDAD DE LA ESTRUCTURA. LAS MAGNITUDES Y DIRECCIONES DE LOS CAMPOS DE ESTOS ELEMENTOS DE TRANSICION ESTAN DISPUESTOS DE MODO QUE EL LIMITE EXTERNO DE LOS ELEMENTOS DE TRANSICION SON SUPERFICIES EQUIPOTENCIALES, Y LA INDUCCION EN LOS ELEMENTOS DE TRANSICION ES CERO. SE PROVEEN ACOPLAMIENTOS (60, 80 Y 81) DE RETORNO INDEPENDIENTES PARA LOS ELEMENTOS MAGNETIZADOS ADYACENTES A LOS ELEMENTOS DE TRANSICION, QUE NO ESTAN EN CONTACTO CON LOS ELEMENTOS DE TRANSICION.
