There are few direct measurements of the intracluster medium (ICM) velocitystructure despite its importance for understanding cluster physics. In lastyears it has been shown that the EPIC-pn energy scale can be calibrated withthe Cu K$alpha$ instrumental line to measure bulk flows of the ICM. Applyingthis technique we have analyzed the velocity distribution of the VirgoCentaurus Ophiuchus and A3266 galaxy clusters. We propose to observe the Galaxycluster A2029 (total exposure time 748~ks) a well-know relaxed cooling corecluster with signatures of a gas sloshing structure to produce high resolutionmaps of the velocity structure of the ICM in the cluster core. Such analysisconstitutes an excellent opportunity to understand the heating/cooling physical processes of such a system. [truncated! Please see actual data for full text]
