We propose to gather spatially resolved spectroscopy of a sample of 33 massive(M_{500}>5e+14 solar masses) clusters detected blindly by Planck and confirmedto-day to be in the redshift range 0.5<z<1. Using for the first time astatistically significant sample in this high-mass, high-redshift regime, wewill study the fundamental scalings between Y_SZ, Y_X and M_500, and thepressure and entropy profiles. This will provide an important probe of thephysics of cluster gravitational collapse and be of large legacy value for thecosmological exploitation of the Planck sample. Complementary VLT observationsare proposed. This proposal is submitted on behalf of the Planck collaboration.

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.
