Abstract (en)
[origin: US4563250A] A method for producing a multichannel plate containing a plurality of generally parallel channels for use in structures for amplifying or converting optical images or other two-dimensional signal patterns by secondary electron multiplication, which method includes: producing a positive mold of the plate, by the steps of: (i) providing a body having the external shape of the plate to be produced and made of a material whose ability to be removed from the body is altered by exposure to a selected radiation; (ii) irradiating the body with the selected radiation in a pattern corresponding to the plate to be produced and in a manner to render the portions of the body corresponding to the channels more easily removable than the remaining portions of the body; and (iii) removing the more easily removable portions of the body; forming a metal negative mold, by the steps of: (i) attaching the positive mold to a metal electrode; (ii) electrolytically depositing metal on the electrode and in the openings created in the positive mold by said step of removing more easily removable portions; and (iii) removing the positive mold from the deposited metal; and forming the multichannel plate from the negative mold.
