Description
Two-phase argon detector is being developed in the Laboratory of Cosmology and Particle physics of the Novosibirsk State University jointly with the Budker Institute of Nuclear Physics. One of the main purpose of this detector is to measure the ionization yield and scintillation efficiency of nuclear recoils, which is of paramount importance for the energy calibration in rare-event experiments such as those of direct dark matter search and coherent neutrino-nucleus scattering. Another purpose is to study the methods of increasing the light yield to decrease the energy threshold of nuclear recoils detection what is the critical task for dark matter search. In this work we demonstrate our the latest achievements in ionization yield measurements and light yield increasing.
