ABSTRACT:
A pick-up tube includes a generally cylindrical envelope having a faceplate at one end thereof and a cathode in the other end. A photoconductive target electrode is adjacent to the faceplate and a mesh assembly is disposed in spaced relation adjacent to the target electrode, between the target electrode and the cathode. The mesh assembly comprises a mesh electrode disposed between a frustro-conically shaped mesh support ring and a dished, spring-like mesh damping ring. The mesh damping ring is fixedly attached at a plurality of points around its periphery to the mesh electrode and the mesh support ring. The mesh damping ring is compressed into a reversal of its dished shape and assumes an undulatory configuration contacting the mesh electrode periodically around the inner periphery of the damping ring thereby retaining the mesh electrode with reduced microphonics.
