Abstract

A novel multi-electron-ion coincidence spectrometer developed on the basis of a 1.5 m-long magnetic-bottle electron spectrometer is presented. Electrons are guided by an inhomogeneous magnetic field to a detector at the end of the flight tube, while a set of optics is used to extract counterpart ions to the same detector, by a pulsed inhomogeneous electric field. This setup allows ion detection with high mass resolution, without impairing the high collection efficiency for electrons. The performance of the coincidence spectrometer was tested with double ionization of carbon disulfide, CS₂ → CS ₂₂₊e^-e^-, in ultrashort intense laser fields (2.8 × 10¹³W/cm², 280 fs, 1030 nm) to clarify the electron correlation below the rescattering threshold.
