WE thermocamera imaging after recovery

While the ITF was locking this afternoon I took some images with the thermocamera installed on WE viewport.

Fig. 1: shows the ITF unlocked.

Fig. 2: shows the ITF locked in CARM_NULL.

Fig. 3: shows the reconstructed image including the baffles done by G. Cagnoli (red one is the inner baffle, cyan one is the outter baffle, the green circle is the mirror surface with 2cm grid lines and the orange sign is the center of the mirror) superposed to the thermocamera images. I also put a red dot to highlight the bright spot seen by thermocamera.

To be kept in mind for comparison when we will be able to do more tests with different offsets.

Here are more pictures of the thermocamera taken today.

Fig. 1: ITF unlocked;

Fig. 2: ITF locked without offset;

Fig. 3: ITF locked with offset applied to WE_Y (12 mm).

No clear difference can be observed between the spots of the two images with the ITF locked. The analysis of the position remains the same of the previous log-entry (#66776).
