We propose to complete the high-quality X-ray observations of a sample of 35intermediate-redshift bright galaxy clusters by observing 4 with XMM-Newton. Thesample is unbiased in X-ray morphology and radio-source content, and is ofsufficient size to permit us to address the extent to which cooling flows arehalted by mechanical energy injected by radio sources, and if the dynamicalstate of the cluster gas correlates with the radio environment. This will beachieved by comparing the X-ray-derived temperature, entropy and pressurestructures with the energy contents, ages and distributions of the radio-sourcecomponents within the clusters.

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.
