General Information (18th November 2008)
The runs were taken after the removal of the mini-frame. This means that only the C-side half-ladders were switched on.
RUN | Trigger Sequence | Trigger Mode | Frequency | Events | ||
---|---|---|---|---|---|---|
63919 | L2a | BC | 4 KHz | 10290 | ||
63914 | L2a | BC | 40 Hz | 10010 | ||
63917 | L2a | BC | 400 Hz | 10101 |
The reconstruction was performed with AliRoot v4-16-Release. The official OCDB files were used from AliEn These files were produced from previous calibration runs.
The analysis of the SSD clusters revealed that we have the following number of golden clusters over all the events for the two runs:
RUN | Layer 5 | Layer 6 | ||
---|---|---|---|---|
63919 | 1201 | 453 | ||
63914 | 554 | 118 | ||
63917 | 632 | 116 |
OCDB files
The OCDB files that were used for the reconstruction of these noise runs come from the run number 63913.
