DESCRIPTION:Speakers: Alexander Bolozdynya (NRNU MEPhI)\nThis is a review 
 of a technology of two-phase emission detectors using liquid noble gases a
 s working media. This kind of detectors invented at MEPhI almost 50 years 
 ago is extremely sensitive to ionization (down to single electrons) and ca
 n be very massive (in ton scale) in order to provide high count rate for q
 uite rare events and organize an active shielding from natural radioactivi
 ty in a wall-les configuration of readout system. The emission detectors f
 ound their unique application in the most sensitive at the moment experime
 nts searching for cold dark matter in the form of weakly interacting massi
 ve particles (WIMPs). The last results of this search are reviewed in this
  paper. The current best limits for the spin-independent interaction of su
 persymmetric WIMPs having a mass in the range between 5 and 1000 GeV/c2 wi
 th nucleons were measured with PANDAX-II detector containing 500 kg of liq
 uid xenon. Emission detectors of the next generation G2\, such as LZ with 
 an active detector mass of 7 tons\, will either unambiguously detect WIMPs
  or rule out all current theoretical predictions for WIMP existence. Detec
 tors of the G3 generation of up to 20 ton will be used for multiple purpos
 es including detection of double beta neutrinoless decay and low-energy ne
 utrinos using effect of elastic coherent scattering off nuclei. This proce
 ss is allowed in the Standard Model and was predicted almost 50 years ago\
 , but so far has not been observed. This process plays an important role i
 n the formation of the Universe and the evolution of stars and can be a se
 nsitive probe of New Physics beyond the Standard Model. Experimental obser
 vation of the effect is very difficult because of the extremely low energy
  deposition in a massive detector medium.  The review includes a descripti
 on of the RED-100 two-phase liquid xenon emission detector especially cons
 tructed to detect the elastic coherent neutrino scattering off xenon nucle
 i when the detector is installed practically on the Earth's surface.\n\nht
