Abstract

"DISPOSITIVO E MéTODO PARA IRRADIAçãO DE FEIXE DE ELéTRON DE PELO MENOS UM PRIMEIRO LADO DE UMA FOLHA CONTìNUA". Dispositivo para irradiação de feixe de elétron de pelo menos um primeiro lado (W~ 1~) de uma folha contínua (W), o dispositivo compreendendo um túnel através do qual a folha continua (W) é adaptada para passar, o mencionado túnel sendo provido com uma porção de entrada (5), uma porção de saída (6) e uma porção central adaptada para receber pelo menos um primeiro emissor de feixe de elétron (2) provido com uma janela de saída de elétron (21) através da qual os elétrons são adaptados para serem emitidos para dentro do túnel. O túnel é inclinado em relação a pelo menos duas localizações em cada uma das porção de entrada (5) e porção de saída (6) de tal modo que qualquer raio-X formado durante a irradiação de feixe de elétron da folha contínua (W) é forçado a incidir na parede de túnel pelo menos duas vezes antes de sair do túnel.
