Taking advantage of the pulsed character of the synchrotron-radiation light, an original experimental setup combining an electron analyzer with a time-of-flight mass spectrometer without angular discrimination, operated with a strong pulsed electrostatic field, has been developed. This allows high counting rates for multiple coincidence measurements Auger electron photoion photoion coincidences. The focus is on the experimental setup; new results obtained with core exited N2O are shown and it is demonstrated how to get more insight into the relaxation dynamics by the selection of the excited state combined with the selection of the final state.
