The H-mode pedestal characteristics on MAST are measured in a variety of Connected Double Null (CDN) and Single Null Divertor (SND) discharges. In CDN discharges the edge density pedestal width in spatial co-ordinates is similar on both the high and low field sides suggesting that the width may be determined by neutral penetration. However, in SND discharges the density pedestal width appears to be a flux surface quantity, which suggests that the scrape off layer may have a role to play in determining the density pedestal width. In both CDN and SND discharges the temperature pedestal width appears to be a flux surface quantity. The pedestal characteristics and edge stability have been studied as a function of ELM type.
