| Abstract | Currently, the largest complete local X-ray cluster sample with full highquality X-ray coverage is HIFLUGCS. Its selection is based on the ROSAT All-SkySurvey and complete X-ray follow-up has been performed with Chandra andXMM-Newton, resulting in numerous applications in cluster physics and cosmology.The combination of high completeness, large sample size, and high qualityfollow-up has been crucial for this wide applicability. Here, we propose asixfold increase in sample size with a new complete high quality sample of ~400clusters, eeHIFLUGCS. We demonstrate that this sample constitutes the ultimatestep before eROSITA and that this significantly increased statistics will enablesubstantial (factor ~3) improvements in precision as well as qualitatively new tests. |

| 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. |
