MIMAC : A Micro-TPC Matrix of Chambers for direct detection of Wimps
نویسندگان
چکیده
The project of a micro-TPC matrix of chambers of He and CF4 for direct detection of non-baryonic dark matter is outlined. The privileged properties of He are highlighted. The double detection (ionization projection of tracks) will assure the electronrecoil discrimination. The complementarity of MIMAC for supersymmetric dark matter search with respect to other experiments is illustrated.The modular character of the detector allows to have different gases to get A-dependence. The pressure degreee of freedom gives the possibility to work at high and low pressures. The low pressure regime gives the possibility to get the directionality of the tracks. The first measurements of ionization at very few keVs for He in He gas are described.

متن کاملDark matter directional detection with MIMAC
MiMac is a project of micro-TPC matrix of gaseous (He, CF4) chambers for direct detection of non-baryonic dark matter. Measurement of both track and ionization energy will allow the electron-recoil discrimination, while access to the directionnality of the tracks will open a unique way to distinguish a geniune WIMP signal from any background. First reconstructed tracks of 5.9 keV electrons are ...
متن کاملSupersymmetric dark matter search via spin - dependent interaction with 3 He
The potentialities of MIMAC-He3, a MIcro-tpc MAtrix of Chambers of Helium 3, for supersymmetric dark matter search are discussed within the framework of effective MSSMmodels without gaugino mass unification at the GUT scale. A phenomenological study has been done to investigate the sensitivity of the MIMAC-He3 detector to neutralinos (Mχ̃ & 6GeV/c 2) via spin-dependent interaction with 3He as we...
