- Title:
- Conical octopole ion guide: Design, focusing, and its application to the deposition of low energetic clusters
- Abstract:
- A design of a radiofrequency (rf) octopole ion guide with truncated conical rods arranged in a conical geometry is presented. The performance is tested in a cluster deposition app. used for the soft-landing of size-selected clusters on well-characterized substrates used as a model system in heterogeneous catalysis in ultrahigh vacuum. This device allows the authors to focus 500 pA of a mass-selected Ni20+ cluster ion beam from 9 mm down to a spot size of 2 mm in diam. The transmittance is 70
