Final Run 9 500 GeV BSMD Status - Willie Leight

BSMD Pedestals and Status for Run 9 pp 500 Data (June 2009, uploaded to offline DB)

The BSMD status analysis for the 500 GeV data proceeds as follows:

  1. Each strip is assigned a status for the whole run from an analysis of fills 10399, 10402, 10403, 10404, 10407, 10412, and 10415.  Pedestals are analyzed using NZS data taken by the BSMD online monitoring, which reads NZS data from evp and subtracts off pedestals which are updated each time a new BSMD pedestal run is taken.  Because NZS data is essentially minbias, high energy tails are analyzed using L2W-triggered data.  Status bits are described in detail here. 
  2. Once each strip has an assigned status, those strips that are not marked as bad move on to the second step.  Here the strips are examined fill-by-fill: for each fill the strip pedestal is QAed by re-applying the pedestal cuts (but not the tail cuts due to lack of statistics), and a new status for that fill is determined.
  3. Next, a pedestal correction is calculated.  The pedestal correction is just the MPV of the pedestal residua if the MPV is greater than the RMS of the pedestal residua. 
  4. Finally, we upload a number of tables to the database: for each BSMD plane there is one that contains a universal status for every strip, one for each fill containing a status for every strip, and one for each fill containing the RMS and pedestal correction for every strip. 

Attached is a pdf that presents the results of this study, including examples.

Table 2: BSMD spectra for 150 eta and 150 phi strips used for status determination for each module (for fills listed above).  Bad strips are identified with the status (in hex): strips with red status are marked bad, strips with green failed a cut but are not necessarily bad.  Note that these spectra are shifted up by 100 on the X-axis so that the pedestal is centered around 100 rather than 0.
