199	Fri Nov 18 09:27:26 2016	Gabriele	General	Measurements	CO2 polishing improves the Q !!
The plot below shows that the Q values of S1600439 improved a lot after the CO2 laser polishing. About 15 modes have Q above 10e6. The first mode at 1kHz has a Q of 37e6, the highest ever measured so far! Here's a comparison of the Q values of this sample before annealing, after annealing and after CO2 polishing.

201	Fri Nov 18 15:48:09 2016	Gabriele	General	Measurements	Microscope inspection of CO2 polished samples
S1600470 For reference, this sample has not been CO2 polished, but it has been annealed and measured. It has quite low Q values. Here are some images of the edges. The first two are taken with light from above. In the second one there some clear red residual, which is also visible as a coloration with the naked eye. The microroughness and some larger defect are well visible. The following images instead are taken with light from below. The red residual is even more evident, and some traces probably due to the machining are clearly visible. S1600479 This sample has been laser polished with a double pass (first at 0.5 mm/s, second at 0.25 mm/s). The first two images are taken with light from above: they are not very clear because of the specular reflection of the lamps. This already indicates that the surface is much smoother. Some defects (bubbles?) are visible close to the main surfaces. The surface quality is more apparent in the following pictures, taken with light from below. The second one is taken where there is a chip in the main surface, and indeed one can see the shading due to the light distortion iduced by the chip. Also a cluster of "bubbles" is clearly visible there. S1600462 This was our first polishing test. It is interesting because the laser tripped during the procedure, so we have a neat transition from the original surface to the polished one. First image taken with light from above, second with light from below

208	Tue Nov 22 14:11:38 2016	Gabriele	General	Measurements	Laser polishing of bad disk improves Q, but they're still not very good
Laser polishing of a sample from the second batch (S1600487, bad Q as out of the box) improves the Q values, but they're still lower than what we got with a good sample (S1600439, first batch)

239	Mon Dec 12 08:42:44 2016	Gabriele	General	Measurements	Thermoelastic losses in Si sample
Following the model from R. Nawrodt et al. Investigation of mechanical losses of thin silicon flexures at low temperatures, CQG 30 (2013) 115008, I predicted the thermo-elastic losses in the Si sample. The model matches quite well the measurements: Here are some details on the model, eq. 1 and 2 of the cited paper: $\phi_{TE}=\frac{\alpha^2 YT}{\rho C_P} \frac{\omega \tau}{1 + \omega^2 \tau^2}$ $\tau = \frac{\rho C_P t_f^2}{\pi^2 k}$ where: alpha = thermal expansion coefficient 2.6e-6/K Y = Young's modulus 150 GPa T = temperature 300 K C_P = specific heat 705 J/kg/K rho = density 2329 kg/m^3 t_f = sample thickness 400 um k = thermal conductivity 130 W/m/K The model is for a cantilever, but it fits well enough for our disk too.

The new laser is still acting up a bit, with a wandering line moving sometimes inside the band. Nevertheless, I could perform the first complete measurement of four samples in parallel. Everything went as expected, there is no visible cross coupling between modes of different disks. The MATLAB code for the analysis is ready and working. Here are the results:
