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