We are currently witnessing the opening of a new survey window to the Universethrough the first surveys for galaxy clusters using the Sunyaev-Zeldovich effect(SZE) contributing to the understanding of the nature of Dark Energy. In AO6 wehave been granted observing time for a 6.3 sqdeg. survey to help in theunderstanding and calibration of these surveys in a region where the three majorsurvey experiments have joint forces for an intercomparison of this new type ofcosmological surveys. The first seven pointings have been conducted and analysedand found to be mostly unuseful due to large contamination by soft protonflares, for reasons explained in detail in the proposal. Here we request thereobservations of the fields lost to enable a timely analysis of the survey data.

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.
