Investigations into the effects of electrostatic charge on the Q factor of a prototype fused silica suspension for use in gravitational wave detectors

Autor: S. M. Twyford, R. Hutchins, J. H. Hough, Sheila Rowan

Publikováno v: Classical and Quantum Gravity. 14:1537-1541

This paper describes some investigations into the construction of a monolithic fused silica test mass suspension for use in interferometric gravitational wave detectors. We summarize results showing that the material Q factor of standard fused quartz

The quality factor of natural fused quartz ribbons over a frequency range from 6 to 160 Hz

Autor: A. McLaren, N. A. Robertson, R. Hutchins, Sheila Rowan, J. H. Hough, S. M. Twyford

Publikováno v: Physics Letters A. 227:153-158

Measurements of the Q factor of oven pulled ribbons of standard fused quartz over a frequency range of 6 t0 160 Hz give results close to those predicted by thermo-elastic damping. This material loss, maintained after breaking and rewelding, is consis
