Abstract
An exploratory experiment is described in which large neon and argon cluster ions are detected with improved sensitivity. The cluster ion beam impinges on a CuBe converter surface, and the positive fragmented and/or sputtered secondary ions, and not the secondary electron, are used for amplification. A drastic change of the mass spectrum from a supersonic expansion is observed.Keywords
