An atomic-beam magnetic resonance (ABMR) system for on-line hyperfine structure measurements in short-lived nuclides

Abstract In order to reach short-lived nuclides far from stability for hyperfine structure investigations, the atomic-beam apparatus formerly at Uppsala has been reconstructed and connected on-line with the ISOLDE isotope separator at CERN. The design and performance of the system will be described with emphasis laid on the on-line oven section and the automic detection and control systems.
