All the goals and tasks of the “Dulkyn” project Ø stage 1st step were successfully accomplished.
As a result of the 2nd step fulfillment, detector “Dulkyn-2” will be created and it will be possible with it to discover violation of Einstein’s equivalence principle or to prove anisotropy of space-time. These discoveries can lead to revolution in study of Universe and to set the beginning of new physics creation. Besides, it is possible to register on “Dulkyn-2” detector the high amplitude gravitational waves from black holes in the center of our galaxy.

As a result of successful fulfillment of the 3rd step, detector “Dulkyn-3” will be created with sensitivity enough for registration of gravitational radiation from binary relativistic astrophysical objects. One of the most actual problems is estimation of resources and prognosis of lithosphere state. Means of estimation and prognosis are based on methods of seismic exploring, magnetic exploring, gravimetric exploring etc. In present project, it is planned to perform at the basis of developing detector the works on the creation of new generation gravimetric devices that have no analogs. Created devices will be able to measure not only vertical and horizontal Earth’s field potential gradients but, also, the second and the third derivatives and their temporal variations and to solve problems that cannot be solved by traditional methods at present time. In applied geophysics, ground measurements of gravity gradients (second derivatives of gravitational potential) can be used for study of near-surface perturbing masses, for detection of voids, for determination of density at vertical profiles. Knowledge of the third gravitational potential derivatives allows the determination of mineral density variation creating investigating anomalies of gravitational potential. Besides, observations are known that allow to affirm that the second vertical derivatives of gravitational potential are also sensitive to upcoming earthquakes. Rising of gravity vertical gradient amplitude could serve as a criterion of upcoming earthquake. For aware registering of these oscillations, it is necessary to have sensitive device that is able to measure in continuous regime variations of the second derivatives. Such devices will give possibility to account the connection of earthquakes with variations of gravitational potential and their influence upon lithosphere, will provide the account and estimations of their consequences. Creation and investigation of new complexes will ensure decreasing of expenses on search, provision and exploitation of mineral deposits by more precise and operative measurements of lithosphere parameters and, also, by measurement of its characteristics not possible for existing gravimeters. Due to their high sensitivity this devices will be able to detect yet unknown phenomena and, moreover, will make possible to achieve survey from space. It can be used for creation of ground-space based of warning for earthquakes. In applied geophysics, the usage of gravity force gradient measurements was considered by academic institutes already in soviet times soon after tragic catastrophe in Armenia in the December of 1988. It is planned in the course of the project to create the production of new devices – compact precision laser-interferometer detectors for the investigation of gravitational field spatial-temporal variations. The defended by a patent “Gravitational-wave detector” device is a prototype for new devices. The project will be realized in three stages. At the first stage (3 years) of the project, laser-interferometer detector will be created with the efficient suppression of technical noises and research on the acquisition of correlation regime for spontaneous radiation in the signal and reference contours of double-resonator laser system (DLS) will be carried out. It is supposed to create at the second stage (3 years) the laser-interferometer complex using correlation regime for spontaneous radiation in the modes of signal and reference resonators of DLS. In the course of the second stage fulfillment, the suppression of natural noises in the double-resonator detector system will be achieved that will allow to reach the record sensitivity in the field of gravimetric devices. The additional goal will be checking of Einstein’s equivalence principle at more high level and detection of gravitational waves. It is supposed at the third stage (5 years) to carry out the development of new generation gravimetric devices, to organize their production and sale. All leading countries are occupied by gravitational research that must yield more deep knowledge of Universe construction. Our approach to study of gravitational phenomena is original and has several advantages over foreign analogs. Acquisition of new results in this field will raise the prestige of country in the international sphere. This new fundamental knowledge will lead to creation of new technologies and, in particular, will lead to discovery of new energy sources, new means of super long communication, principally new measurement devices for geological survey and astronavigation. The carrying out of this work itself will allow to use obtained technological experience in many fields of industry that will rise without doubts technological level of the country.
