DIM is mounted on the top surface side of Philae and it is aimed to derive the physical properties and the flux of the millimetric dust particle population that moves near the surface of the nucleus of the comet 67P/Churyumov-Gerasimenko (67P). We performed a series of calibration experiments at temperatures between -40º C and -20º C to analyse the response, the performance and the detection range of DIM. The experiments mainly comprise impacts with spherical ice particles (radii of nearly 0.5 mm) on the sensor plates at different impact speeds and with different impact directions. The landing of Philae on the nucleus of the comet 67P is expected to take place in mid November of this year and we also hope to show the first analyses of the early data from DIM.
