Abstract

A charged particle collecting body forming part of an electrode comprises a three dimensional network defining a multiplicity of interconnecting free cells. The dimensions of the cells are selected to permit a major portion of charged particles incident thereon to penetrate a number of free cells before impinging on a strut of the three-dimensional network.
