14 February 2007 Calorimeter commissioning meeting, CERN E.Guschin (INR,Moscow) Digital camera with LED monitoring Status: Photographs of SPD are completed from both top and bottom. The PS1 and PS2 are done in the bottom part. To go ahead the problem is an access. The quality of pictures is good except in the first part (SPD5-8 bottom), where it was luck of experience, so the quality was just satisfactory. The first look shows correlation between installation data and cosmic test and current measurements. The total number of not working LED’s is ~0.5%, that was at the installation. Some problems with fibres are identified. The broken fibre shown on SPD6 bottom is confirmed with cosmic data. Further analysis is ongoing but time consuming.

14 February 2007 Calorimeter commissioning meeting, CERN
E.Guschin (INR,Moscow)
Digital camera with LED monitoring
Status:
Photographs of SPD are completed from both top and bottom. The PS1 and PS2 are done in the bottom part. To go ahead the problem is an access.
The quality of pictures is good except in the first part (SPD5-8 bottom), where it was luck of experience, so the quality was just satisfactory.
The first look shows correlation between installation data and cosmic test and current measurements. The total number of not working LED’s is ~0.5%, that was at the installation.
Some problems with fibres are identified. The broken fibre shown on SPD6 bottom is confirmed with cosmic data. Further analysis is ongoing but time consuming.
