ABSTRACT

The chamber for direct detection of WIMP with mass ≤ 0.5 Gev/c² was developed. The chamber is filled with gas mixture Ne+10%H₂ (0-1bar)+0,15ppm Ge(CH₃)₄. For events detections used GEM+pin-anode, which provides the energy threshold about eV. The electron background is suppressed owing to photosensitive addition Ge(CH₃)₄ . It is proposed also for direct detection of WIMP the liquid argon chamber with H₂ dissolved in liquid argon at a concentration 100ppm+0,015ppm Ge(CH₃)₄.
