In electron spectroscopy, multi-channel detection combined with intense radiation sources provides the optimum experimental configuration. Building on the 5 mm, 192-channel ion detector developed at Aberystwyth, longer arrays have been fabricated for the detection of electrons in a commercial hemispherical analyser. The performance and reliability of a 10 mm, 384-detector array is discussed and the first array-detected photoelectron spectroscopy data for single-crystal diamond are presented. In scanning mode, the detector shows a large improvement compared to single channeltron detection and this improvement allows data to be collected in snapshot mode (1 s per spectrum) to enable real-time measurements.
