Abstract
A mount for attaching an electrode system, which focusses electrons generated upon the incidence of x-rays on an input luminescent screen onto an output luminescent screen, to an exterior housing of the intensifier is formed by annular electrodes which telescopically engage and which are held together at overlapping regions by a clamped connection. The mount has a simple structure which minimizes the possibility of the electrode system getting out of adjustment, and also significantly decreases the assembly time during manufacture of the x-ray image intensifier.
