Through a multiwavelength program of ground-based optical and near-infraredimaging plus space-based X-ray imaging with Swift, we have identified a numberof rich, massive, X-ray--emitting clusters among the unconfirmed Planck clustercandidates. We have selected the ten most promising new clusters for observationwith XMM this cycle. All have Planck signal-to-noise ratios greater than 5 andsignificant X-ray flux. The proposed observations will provide the firstaccurate masses of these clusters based on multiple X-ray mass proxies and willallow determination of their dynamical states (merger vs. relaxed systems).

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.
