Description

In order to perform Directional DM detection, low energy nuclear recoil tracks have to be detected. The MIMAC collaboration has recently reported the first detection of 3D nuclear tracks coming from the Radon progeny confirming the possibility to perform this kind of measurement with an ionization quenching measurement on these heavy nucleus. The nuclear recoils produced by monochromatic neutron fields have been detected by a MIMAC chamber allowing the experimental determination of the electron-nuclear recoil discrimination at the same time that the angular distribution of the Fluorine recoils produced by the neutron elastic collision has been experimentally described. A new facility called COMIMAC has been developed at the LPSC (Grenoble) to perform the 3D characterization of nuclear recoil tracks of known kinetic energies. The first measurements will be reported showing clear differences with respect to the best simulation available.
