      abstract     = {We demonstrate the feasibility of coincidence measurements
                      on a conventional transmission electron microscope,
                      revealing the temporal correlation between electron energy
                      loss spectroscopy (EELS) and energy dispersive X-ray (EDX)
                      spectroscopy events. We make use of a delay line detector
                      with ps-range time resolution attached to a modified EELS
                      spectrometer. We demonstrate that coincidence between both
                      events, related to the excitation and deexcitation of atoms
                      in a crystal, provides added information not present in the
                      individual EELS or EDX spectra. In particular, the method
                      provides EELS with a significantly suppressed or even
                      removed background, overcoming the many difficulties with
                      conventional parametric background fitting as it uses no
                      assumptions on the shape of the background, requires no user
                      input and does not suffer from counting noise originating
                      from the background signal. This is highly attractive,
                      especially when low concentrations of elements need to be
                      detected in a matrix of other elements.},
