Abstract:
A novel experiment for direct searches of the Dark Matter with liquid
argon double-phase
chamber with a mass of liquid Ar up to several hundred tons is proposed. To
suppress the $\beta$-, $\gamma$- and $n_0$-backgrounds, the comparison of scintillation and ionization signals for
every event is
suggested. The addition in liquid Ar of photosensitive Ge(CH$_3$)$_4$ or C$_2$H$_4$ and
suppression of
triplet component of scintillation signals ensures the detection of
scintillation signals with high
efficiency and provides a complete suppression of the electron background. For
the detection of
photoelectrons and ionization electrons, highly stable and reliable GEM
detectors must be used.
