Title:
リフレクトロンレンズとして用いられる導電性チューブ
Document Type and Number:
Japanese Patent JP4826871
Kind Code:
B2
Abstract:
A reflectron lens and method are provided. The reflectron lens comprises a tube having a continuous conductive surface along the length of the tube for providing an electric field interior to the tube that varies in strength along the length of the tube. The tube may comprise glass, and in particular, a glass comprising metal ions, such as lead, which may be reduced to form the conductive surface. The method includes a step of introducing a beam of ions into a first end of a dielectric tube having a continuous conductive surface along the length of the tube. The method further includes a step of applying an electric potential across the tube to create an electric field gradient that varies in strength along the length of the tube so the electric field deflects the ions to cause the ions to exit the tube through the first end of the tube.
