报告题目

Low-Frequency Tensor Gravitational-Wave    Detector With Superconducting Instrumentation

报告内容

The recently proposed terrestrial low-frequency gravitational-wave (GW) detectors offer the possibility of studying GW physics in a lower frequency range than the audio band km-scale interferometers (LIGO, VIRGO and KAGRA). The superconducting gravity gradiometer (SGG) is a GW strain sensor in the 0.01 Hz to 1 Hz band. A low-frequency GWdetectorbased on the concept of the SGG, called “a tunable free-mass GW detector,” was proposed as early as in 1979 by Wagoner, Will and Paik.  We outline the design for a new type of low-frequency GW detector based on the SGG approach.  By using six levitated test masses, a “spherical” GW detector capable of detecting the source direction and wave polarization could be constructed.  The design concept of a new detector that could reach a sensitivity of 10-20 Hz-1/2at 0.1 Hz is discussed.
