Non-destructive detection of large molecules without mass limitation

The problem for molecular identification knows many solutions which include mass spectrometers whose sensitivity depends on the performance of detector involved. purpose this article is to show by means dynamics simulations, how a laser-cooled ion cloud, confined in linear radio-frequency trap, can reach ultimate providing detection individual charged heavy ions. In our we model Ca + ions as two-level atoms, thanks set constant and time oscillating electrical fields. A singly-charged with 10 6 amu propelled through cloud. induced change fluorescence rate lather used signal. We that signal due significant temperature variation triggered Coulombian repulsion amplified heating trap itself. identify optimum initial energy be detected furthermore, characterize large range confinement voltages.
