Results from the run 36327

1. General Information

RUN 36327
Events 1524

SSD LDCs 3
Duration 5:31:23

2. Detector Configuration

Below you can find the snapshot of the SSD FSM showing the detector configuration for this run.

3. OCDB files

The OCDB files that were used for the reconstruction of this run were produced by the SSD DA during the pedestal run with the number 36256. The plots below show the map of the bad channels:

In addition, we also show the bad channel list that from the pedestal run 36100 that was also used for further tests.

4. Analysis of clusters

  • Using the OCDB bad channel list of run 36100

This is the cluster charge distribution when using the bad channel list of the wrong pedestal run!

  • Using the OCDB bad channel list of run 36256

This is the cluster charge distribution when using the bad channel list of the correct pedestal run!

Based on the previous strange results, we created each time a new bad channel list which consisted of:

    • All the modules that have at least 90% bad p or n side strips
    • All the modules that have at least 10% bad p or n side strips
    • All the modules that have at least 2% bad p or n side strips
    • All the modules that have at least 1% bad p or n side strips

The results of the cluster charge distribution after the reconstruction with the previous different lists are shown below.
