We checked the HWS-DET SLED beam centring on the camera comparing it with the one acquired before the intervention on SDB1 - see Fig. 1.
The SLED beam is still correctly visible on the HWS-DET CCD.
This afternoon, we replaced the CCD with the HWS (see attached figure).
In preparation for tomorrow's measurement with HWS-INJ, we switched off the HWS-DET SLED.
