We propose a 130ks observation of the X-ray brightest cluster above z=0.1,PKS0745-191. In the absence of heating there should be cooling at 1000 Msun/yr.XMM shows the presence of central cool gas and Chandra the location of feedback.We will examine the central temperature distribution with RGS to study thefeedback-cooling connection. In addition, most of r_200 can be studied in asingle pointing to examine clumping. We will examine the surface brightnessfluctuation spectrum as a function of radius to connect to cluster-wide andAGN-related turbulence.

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.
