Abstract	With the paper A Hubble Diagram for Quasars Risaliti and Lusso (2015)established quasars as a kind of standard candles to measure cosmologicalparameters. This method is of utmost importance as it allows to measure thecosmological parameters for different redshift ranges and to test for anevolution of the parameters over cosmological time. We propose to observe 131quasars at a redshift higher than 5.6, i.e. nearly all known such quasars(Banados et al., 2016) not yet observed in X-ray. The aim is to measure thecosmological parameters with high precision in the redshift range from 5.6 to7.0 for the first time. This redshift range is not accessible with any othermethod, e.g. supernovae, clusters of galaxies, microwave back ground or baryon

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
