High redshift quasars probe the formation and evolution of supermassive black holes openParSMBHsclosePar at early cosmic time. Here we propose XMM-Newton observations of J0439 at z = 6.5 comma the most distant lensed quasar known to date. Aided by a magnification factor of virgul50 comma it is the brightest quasar in optical and FIR at z>6 and unique target for the study of SMBH accretion at the reionization era comma with typical BH mass but extremely high anticipated X-ray flux. With only 90 ks net exposure comma a high quality X-ray spectrum with total counts of virgul8000 counts can be obtained comma providing a high S-N X-ray view of an early SMBH for the first time. We will search for the ultra-fast outflows and measure the X-ray luminosity comma spectral slope comma coronal properties and optical-to-X-ray SED of this quasar.
