Abstract	We propose a 130ks observation of the NLS1 TonS180 - which has one of thestrongest soft X-ray excesses, implying strong reprocessing, but no previouslong XMM observation - to determine whether, contrary to previous CCF results,it shows the negative high frequency spectral lags expected from such a source.We will model the lags to measure BH spin (ie inner disc radius) and thusconfirm or deny blurred disc reprocessing models for the soft excess and thealso the high spin explanation for NLS1s. We also determine BH mass, which ispresently poorly known. From the PSD we will determine whether TonS is only thesecond very high state AGN known and, using its very high accretion rate, testM/mdot/timescale scaling relationships for AGN.

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.
