Very high quality factor measured in annealed fused silica

We present the results of quality factor measurements for rod samples made of fused silica. To decrease the dissipation, we annealed our samples. The highest quality factor that we observed was Q = (2.03 ± 0.01) × 108 for a mode at 384 Hz. This is the highest published value of Q in fused silica measured to date.
