GEM-based detectors for direct detection of low-mass WIMP, solar axions and narrow resonances (quarks)
B. M. Ovchinnikov, V. V. Parusov
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…
Detection chamber for search of low Mass WIMP and solar axions
B. M. Ovchinnikov, V. V. Parusov
A chamber for direct detection of WIMPs with masses < 10 GeV/c2 and solar axions is developed. The chamber is filled with a gas mixture of H2 +3ppm TMAE (1,5,10 bar), or D2 + 3ppm…
Massive liquid Ar and Xe detectors for direct Dark Matter searches
B. M. Ovchinnikov, Yu. B. Ovchinnikov, V. V. Parusov
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 b-…
Gas Electron Multiplier detectors with high reliability and stability
B. M. Ovchinnikov, V. V. Parusov, Yu. B. Ovchinnikov
The Gas Electron Multiplier detectors with wire and metallic electrodes, with a gas filling in the gap between them were proposed and tested. The main advantage of these Gas Electr…
Multi-channel gas electron multiplier with metallic electrodes
B. M. Ovchinnikov, V. V. Parusov, Yu. B. Ovchinnikov
The design of multi-channel gas electron multiplier (MGEM) with metallic electrodes is proposed, produced and tested. The electrodes of MGEM are produced from the brass plates with…
Multi-channel wire gas electron multipliers with gaps between the electrodes of 1 and 3mm
B. M. Ovchinnikov, V. V. Parusov, Yu. B. Ovchinnikov
Multi-channel wire gas electron multipliers (MWGEM) with gaps between the electrodes of 1 and 3mm were investigated. The chamber of the MWGEM was filled with pure commercial neon g…
A multi-channel wire gas electron multiplier
B. M. Ovchinnikov, V. V. Parusov, Yu. B. Ovchinnikov
A novel and relatively simple method of production of electrodes for a multi-channel wire gas multiplier is developed. Two modifications of the multipliers have been tested: with a…
Wire GEM detector
B. M. Ovchinnikov, V. I. Razin, A. I. Reshetin +1
A wire GEM (WGEM) detector with a gas gap between meshes was constructed. The detector provides the amplification 5x10E5 for the gas mixture of Ar +20% CO2 at atmospheric pressure.…
RETGEM with polyvinylchloride (PVC) electrodes
V. I. Razin, B. M. Ovchinnikov, A. I. Reshetin +1
This paper presents a new design of the RETGEM (Resistive Electrode Thick GEM) based on electrodes made of a polyvinylchloride material (PVC). Our device can operate with gains of…
