15. Cylindrical or wedge spacers are frequently used as wire standoffs for test mass suspension system.
16. The data for the invar wire show that there is larger scatter for different pieces of wire than variation for different measurements and modes, and the hardened steel clamps tend to give higher Qs than the stainless steel clamps. This could indicate existence of clamp losses which depend on a material of the clamp and a subtle condition of clamping. Since invar has much higher measured Qs than the other wires, any variation in Q due to subtle clamping effects will be more apparent than with the other wires.
