Broken Bonds
Noise data available offline
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:
- create a new directory e.g:
lhcb@ckm:~/noise/symLinks
- create symbolic links to all the .root files you want to include in the plots. (The script createSymLinks.sh might be useful).
Noise plots
Plots were generated for the following sectors affected by broken bonds:
| TELL1 | Sector | first observed | Taken out | noise pattern sector 2008 | noise distributions / noise vs. time 2008 | noise pattern sector 2009 | noise distributions / noise vs. time 2009 |
| plot (y/n) | plots for broken channels | plot (y/n) | plots for broken channels | ||||

noise pattern: noise as a function of the channel number (a plot for each run available) plots for broken channels: 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. Files in:
lhcb@ckm:~/noise/VFS400_NOTP/rootFiles/2008
lhcb@ckm:~/noise/VFS400_NOTP/rootFiles/2009
- Noise Plots - How to generate noise plots.
Count low noise channels
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>
