Using a magnetic bottle time-of-flight electron spectrometer we have measured double photoionisation spectra of N 2 and CO 2 covering the range from threshold up to the triple ionisation energies. The experiments demonstrate the use of a new asynchronous chopper in eight-bunch mode of the synchrotron radiation source SOLEIL. For CO 2 2+ some broad bands in the Auger spectra are found to have multiple resolved counterparts in the photoionisation spectrum. All the bands in the Auger spectra have counterparts in the photoionisation spectra, where extra bands attributed to triplet states are present. In the spectrum of N 2 2+ we suggest reassignment of one band. [ABSTRACT FROM AUTHOR]
