  Gas electron multipliers (GEMs) with wire (WGEMs) or metal electrodes
(MGEMs), which don't use any plastic insulators between electrodes are created.
The chambers containing MGEMs (WGEMs) with pin-anodes are proposed as detectors
for searching of spin-dependent interactions between Dark Matter (DM) particles
and gases with nonzero-spin nuclei (H2, D2, 3He, 20Ne, CF4, CH4, etc.). In this
paper, we present a review of such chambers. For investigation of the gas
mixtures Ne+10%H2, H2 (D2) +3ppmTMAE, the chamber containing WGEM with
pin-anode detection system was constructed. In this paper we present the
results of an experimental study of these gaseous mixtures exited by an
{\alpha}-source. Mixture of Ar + 40 ppm C2H4 and mixture 50% Xe + 50%CF4 have
been investigated. The spatial distributions of photoelectron clouds produced
by primary scintillations on {\alpha}- and \b{eta}-particle tracks, as well as
the distributions of photoelectron clouds due to photons from avalanches at the
pin-anode, have been measured for the first time. In our experiments as another
filling of the chambers for search of low-mas WIMP (<10 GeV/c2), solar neutrino
and solar axions with spin-dependent interaction we propose to use the
mixtures: D2 +3ppmTMAE, 3He + 3%CH4, 20Ne + 10%H2, at pressure 10-17 bar. And
in our experiment with liquid gases is used the mixtures with 19F (LAr + CF4,
LXe + CF4) and mixture LCH4 + 40ppm TMAE. The time projection chamber (TPC)
with the mixture D2 + 3ppmTMAE filling allow to search of spin-dependent
interactions of solar axions and deuterium. As well as we present the detecting
systems for search of narrow pp-resonances (quarks) in accelerators
experiments.
