Fig. 4From: Design and characterization of a linear quadrupole ion trap for high-resolution Coulomb-crystal time-of-flight mass spectrometry a Molecular dynamics simulations of 100 Ca + (blue) and 100 ions of mass 80 u (red) at different DC offset potentials applied to the extraction meshes. b Time-of-flight traces of Coulomb crystals consisting of Ca +, CaO + and CaOH + ions at different DC offset potentials applied to the extraction meshes prior to the ion extraction. Each trace is the average of 5 measurementsBack to article page
