“ Dulkyn” Gravitationfl Wawe Research Scientific Center of the AS RT.

1. “Dulkyn” Gravitationfl Wawe Research Scientific Center of the AS RT. • The gravitational wave detector “Dulkyn” • Address:Russia, 420111, Republic of Tatarstan, Kazan, P.B. 595 • www.Dulkyn.org.ru • Dulkyn@mail.ru • (+7 843)-272-42-66

3. Project realization location and equipment • Project will be realized in the United Experimental Laboratory of Gravitational-Optical Research on the basis of Scientific-Industrial Association "State Institute of Applied Optics" which will be formed by partial conversion of institute`s facilities into the extradepartamental organization with strictly peaceful orientation under support of Scientific Centre of Gravitational-Wave Research "Dulkyn" on terms of institute of Academy of Sciences of Republic of Tatarstan. • SC GWR "Dulkyn" contains the Department of Theoretical Problems of Gravitation-Wave Physics, comprising high-skill specialists on investigation of gravitation-wave fields. FSIC SIAO (transliterated russian abbreviation is GIPO) possesses the materials and equipment for carrying out the precise interferometric experiments: specialized vibro- and thermostabilized chambers at the depth of 12 meters, integrated and fiber-optic elements, electron systems for automatized measurements, machine-tools for processing the optical fibers.

4. Project goals are the following: • Elaboration and creation of unique complex of laser-interferometric equipment of new generation for implementation of presented by the SC GWR “Dulkyn” Programme of fundamental and application research, integrating the achievements of modern laser physics and optical professional equipment, as well as the efforts of geological, geophysical, seismological, astrometric and geodesic services. Final purpose of the research programme is the discovery of gravitational waves, study of the local and global structure, time variations and spatial anomalies of gravi-inertial field.

5. Main trends of investigation • Detection of periodic gravitational radiation from relativistic astrophysical objects. • Creation of compact laser-interferometric detector of periodic gravitational radiation; • Detection and research of the gravitational wave properties; theoretical and experimental testing the bases of modern theory of gravitation and the newest conceptions in cosmology and astrophysics.

6. Main trends of investigation • Investigation of infra-low-frequency variations of Terrestrial gravity field • Monitoring of infra-low-frequency variations of the global potential of the Earth, long-term and short-term forecast of seismic activity, reconstruction of the dynamic phenomena taking place in the inner stratums of the planet and of terrestrial potential variation; • Measuring the first, second and third derivatives of the gravity field potential, reconstruction of the local structure of the gravity field, applications to the problems of geology prospecting and evolution of the oil-bearing strata.

7. Development stage • A special vacuum chamber for isolation of the laser system from external environment with diameter of 1.7 m and 0.67 m in height has been made. The residual pressure inside the chamber does not exceed 10-3 torr. • The adjustment and debugging of the servos of the frequency and phase stabilization of the generated optical radiation have been carried out. • Developed an made a special system for measurement of DCLS output signals and a precision phase modulator for imitation of valid signal with the purpose of gauging and certificating the GW detector “Dulkyn”. • The test records of the vacuum system and frequency-phase stabilization system are available. • Legal protection • The basic ideas and calculations are published in more than 80 articles and protected by 11 Russian patents on inventions.

8. Cooperation proposals • Participation in: • joint research and experiments; • creation of compact laser-interferometric detectors of periodic gravitational radiation; • grid the world net of detectors; • astronomic, geodesic and geophysical applications.
