Phys. Rev. D 53, 5377–5381 (1996)First tests of a truncated icosahedral gravitational wave antennaReceived 30 November 1995; published in the issue dated 15 May 1996 We constructed a prototype of a spherical gravitational wave antenna in the shape of a truncated icosahedron. We used it to test several aspects of the practicality of a spherical multimode antenna. We successfully tested a first-order direction finding algorithm, which uses fixed linear combinations of six motion sensor responses to infer the relative amplitudes of the quadrupole modes and then the location of a test impulse. This method is immediately applicable to the determination of the direction of a gravitation wave. © 1996 The American Physical Society URL:
