We propose to continue our programme of deep RGS observations by observing oneof the X-ray brightest galaxy clusters AWM7, and the highly-luminous, high starformation rate cluster Zw3146. We will limit or measure the mass depositionrates in AWM7 and Zw3146 with high accuracy to a value close to the starformation rate. These objects will be added to an existing successful programme,spanning a large range in temperature and mass, to make definitive statementsabout the range of temperature in clusters and the level of cooling. Theseobservations will exploit the unique capability of the RGS, and build on one ofXMM.s major discoveries.

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.
