3. Analysis of clusters

Here are some histograms obtained with the official offline QA for the SSD clusters. In all plots we see the accumulated statistics from all the events of this run. There was a selection on the golden clusters.

Please pay attention to the spike on the right hand side plot. It comes from module 1510 of ladder 610 of the C-side. This ladder was having a bad day during the 17th of June!

3. MOOD screenshot

Below you see a snapshot of MOOD showing the occupancy of the module 1510 which belongs to the C-side ladder 610 and gives the spike in the module ID distribution plot for the cluster position. The run was a standalone one taken the morning of the 18th of June without storing the file in the LDC (online monitoring).

For completeness, below you can find the occupancy plots for this module taken at different times:

  • A standalone run taken after the pedestal run during the night of the 17th of June

  • A standalone run taken a few minutes after the previous run

  • A standalone run taken after the pedestal run 39753

This ladder had particular problems with its current throughout the night of the 17th of June (unstable current). During the 18th of June everything went back to a normal behavior.
