The following data was processed using STNZSMonitor by Mark Tobin:

• 2008 and 2009 data, files abailable in :

  lhcb@ckm:~/noise/VFS400_NOTP/rootFiles

• 2010 data (until june) was taken with the TEST recipe, files in:

  lhcb@ckm:~/noise/TEST/rootFiles

How to reate a compilation of noise data:

1. create a new directory e.g:

   lhcb@ckm:~/noise/symLinks

2. create symbolic links to all the .root files you want to include in the plots. (The script createSymLinks.sh might be useful).

• Noise pattern (sector): For all sectors listed above the noise pattern (noise as a function of the channel number) of the given sector is plotted for each run listed in the directory symLinks. HV is on (250 V) and there are >=4k Evts used to compute the noise. The plots are available

  <code> lhcb@ckm:~/noise/symlinks/plots/NoisePlots_t{TELL1NUMBER}_s{SECTRORNUMBER}/

• Plots for broken channels (and/or candidates): for all channels having bonds on the innermost bond row two plots (noise distribution, noise as a function of the time) were generated in the range indicated in the table above. Plots available:

   lhcb@ckm:~/noise/symLinks/plots/ 

• How to make these plots

brokenbonds

The plot shows the total number of low noise channels on TELL1 2, 3, 5, 6, 10, 35 and 46 as a funtion of the run number. All NZS400_NOTP-data available was taken into account.

• More plots for all the NZS files of 08 & 09 are available in directory:

  lhcb@ckm:~/noise/VFS400_NOTP/plots/nBadChannelsAllFiles08And09>

• More plots for data taken with high voltage are available in directory:

  lhcb@ckm:~/noise/VFS400_NOTP/links_hvOn/nBadChannels>
