2. Normalising LHC BLM data
Goal: Providing dose levels/integrated intensity (Gray/proton second )
dose levels/integrated luminosity (Gray/fb-1)
LHC LDB/MDB
Luminosity
Intensity
Normalised data
Report
BLM data
Ongoing work:
Creation of automated scripts
Data retrieval
Intensities 2016
Luminosities 2016
BLM
RadMon
Analysis scripts
Plotting tools
Publish reports Weekly

3. Normalising LHC BLM data
LDB variable used for the LHC BLMs: BLM_name:DOSE_INT_HH.
Fine for data from 2016
Issues for data from 2015
Overhaul of the scripts will solve the issue.
Collaboration with Chen Xu
New features:
Variable integration intervals
Selecting beam modes
Selecting beam energies
Calculation of the lost particle intensities per fill

4. Normalising LHC BLM data
Next steps:
Investigation of data retrieval routines.
Data retrieval
Upgrade of the local data base
Update of the existing analysis modules
No time estimate yet (O(weeks)).
Expand the framework to injectors.
Work started on the SPS data

5. TCL settings right of IR5 beam 1
Open: IP5 TCL 6 is open TCL 5 is closed.
Closed: IP5 TCL 6 is closed TLC 5 is open.
Until TCL 4 losses similar (upstream).
From cell 9 on losses similar (downstream).
Settings in IR1 stationary.
 No changes visible.

10. Loss symmetries at IR1
Data: Total data from 2016 ( to )
Beam 1: filtered BLM list for BLM..B1
Beam 2: filtered BLM list for BLM..B2
Beam 2.mirrored: beam2*(-1)
Interpolation: python interpolate.interp1d()
Ratio: division of the interpolation functions f1(beam1) and f2(beam2.mirrored)
Mean: mean of the ratio values, check for symmetry
Std: standard deviation of the ratio values

Loss patterns left and right of the IPs for the two beams are very symmetric.
Plots for the other IPs can be provided.
