We present observations from the Small Array of the Arcminute MicrokelvinImager (AMI) of eight high X-ray luminosity galaxy cluster systems selectedfrom the Local Cluster Substructure Survey (LoCuSS) sample.We detect theSunyaev-Zel'dovich (SZ) effect in seven of these clusters. With the assumptionsthat galaxy clusters are isothermal, have a density profile described by aspherical b -model and obey the theoretical M-T relation, we are able to derivecluster parameters at r200 from our SZ data. With the additional assumption ofhydrostatic equilibrium we are able to derive parameters at r500. We presentposterior probability distributions for cluster parameters such as mass, radiusand temperature (TSZ, MT). Combining our sample with that of AMI Consortium:Rodr'\iguez-Gonz\'alvez et al. (2011) and using large-radius X-ray temperatureestimates (TX) from Chandra and Suzaku observations, we find that there isreasonable correspondence between TX and TSZ,MT values at low TX, but that forclusters with TX above around 6keV the correspondence breaks down with TXexceeding TSZ, MT; we stress that this finding is based on just ten clusters.
