We have recently re-built our Auger photoelectron coincidence spectroscopy (APECS) system at Murdoch University. The new instrument counts at much higher rates and with greater energy resolution. With this we have looked again at the APECS spectra from Cu. We have been able to see more clearly the L2-L3V-VV(V) Coster-Kronig satellite and, in a reverse experiment, to find out which parts of the photoelectron spectrum are responsible for the satellite. The data also show the importance of shake-up/off processes in the background of the L3-VV line. We will present information on the changes we have made to the apparatus as well as the implications of the data we have collected with it.
