The remnant of the supernova SN1006 is the best example of a non thermal SNR. In X-rays, both the thermal emission from the hot gas and the synchrotron emission from the accelerated electrons are measured. Because it is relatively isolated and its morphology is quite simple, it is the best object for comparing with theoretical models of cosmic-ray acceleration. A key prediction of those models is gamma-ray emission from pion decay due to the interactions between the accelerated protons (and heavier ions) and the thermal gas. No gamma-ray emission was detected from SN1006 yet, but predicting the level it should have is important. The most important ingredient for predicting the gamma-ray flux is the gas density inside the SNR. This is something that can be measured in X-rays. Using XMM-Newton X-ray observations, we present a study of this density by modelling the rims where the thermal emission dominates (i.e. the North-West and the South-East) with a plane parallel shocked plasma model, plus another component for the ejecta. In order to map the two rims and to have a better statistic we combined several observations of the remnant. The density found is low and is compatible with the non detection of the remnant by the HESS gamma-ray observatory.
