Abstract

<B>TUBO DE RAIOS CATóDICOS<D>, inclui um painel retangular no qual uma tela de fósforo é formada, um gargalo no qual está posicionado um canhão condensador de elétrons emitindo três feixes de elétrons, e um funil. O funil, que é composto por uma porção principal e uma porção cónica, onde um contorno da seção tranversal da dita porção cónica é uma forma não circular e a distância perpendicular do eixo do tubo ao contorno ocorre na direção de uma diagonal principal. Esta diagonal forma um ângulo <sym>' com o respectivo eixo horizontal de acordo com a seguinte inequação: <sym> - {4.3+(S/3.8)} < <sym>' < <sym> + {4.3+(S/3.8)} onde <sym> é o ângulo em graus que a diagonal da face do painel forma com o respectivo eixo horizontal; S é a distância em mm entre os centros dos orifícios de passagem dos elétrons do canhão condensador de elétrons.
