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 vibroand 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.
Project goals are the following:
• Elaboration and creation of
unique complex of laserinterferometric 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.
• 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.
Main trends of investigation
•
•
•
Investigation of infra-lowfrequency variations of Terrestrial
gravity field
Monitoring of infra-low-frequency
variations of the global potential
of the Earth, long-term and shortterm 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.
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.
