Wide bandwidth dual acoustic gravitational wave detectors
In a “dual” detector a wideband sensitivity is obtained by measuring the differential displacement, driven by the gw wave, of the facing surfaces of two nested massive bodies mechanically resonating at different frequencies. By the use of the recently proposed “selective readout” scheme, capable of specifically selecting the signal contributed by the vibrational modes sensitive to the gravitati...
متن کاملSpherical Gravitational Wave Detectors
Resonant bar gravitational wave detectors have improved greatly over the last 40 years but are currently completely outperformed by laser interferometer detectors. Spherical detector configuration has several advantages over conventional bar detectors and can be considered as the next generation of resonant gravitational wave antenna. In this report, I will give a brief introduction to gravitat...
متن کاملGrAVitAtionAl WAVE dEtEctors
uncertainty from having a discrete spacetime has been reduced by a factor of three. This correspondingly reduces the error on extrapolating from the unphysical lattice world to the real world. Until now, this uncertainty has been a problem for the charm quark because its relatively large mass gives it a shortwavelength quantum field that can ‘see’ the lattice spacing. This improvement also help...
متن کاملSimulation of Gravitational Wave Detectors
A simulation program which provides insight in the vibrational properties of resonant mass gravitational radiation antennas is developed from scratch. The requirements that are set necessitate the use of an explicit nite element kernel. Since the computational complexity of this kernel requires signi cant computing power, it is tailored for execution on parallel computer systems. After validati...
متن کاملA hollow sphere as a detector of gravitational radiation
The most important features of the proposed spherical gravitational wave detectors are closely linked with their symmetry. Hollow spheres share this property with solid ones, considered in the literature so far, and constitute an interesting alternative for the realization of an omnidirectional gravitational wave detector. In this paper we address the problem of how a hollow elastic sphere inte...
