W-analysis

Setup

• Create access to lintrack: mount, link, whatever suits you best. I linked it to

  ln -s /user/slops/data/LHC_DATA/OP_DATA/Betabeat lintrack

• Get modified Beta-Beat.src:

  git clone -b getsuper_accmodels git@github.com:pylhc/Beta-Beat.src.git

• pip install omc3 into your python env

Procedure

omc3

• Copy command.run, delete the logging part (ideally leave only the call to python -m omc3, but you can leave ssh optics2)
• Change outpudir to the new one (otherwise it would overwrite the original, BAD!!!!)
• Add --chromatic_beating The file should now look like this:

/afs/cern.ch/eng/sl/lintrack/omc_python_edge/bin/python -m omc3.hole_in_one \
  --optics \
  --files \
  /user/slops/data/LHC_DATA/OP_DATA/Betabeat/2023-08-30/LHCB1/Measurements/Beam1@BunchTurn@2023_08_30@17_28_14_348/bunchid0_Beam1@BunchTurn@2023_08_30@17_28_14_348.sdds \
  --outputdir inj \
  --calibrationdir /afs/cern.ch/eng/sl/lintrack/LHC_commissioning2017/Calibration_factors_2017/Calibration_factors_2017_beam1 \
  --accel lhc \
  --model_dir /user/slops/data/LHC_DATA/OP_DATA/Betabeat/2023-08-30/LHCB1/Models/b1_inj_28_31 \
  --year 2022 \
  --chromatic_beating \
  --beam 1

• rerun (e.g. chmod and ./command.run)

Beta-Beat.src

• Same as for omc3: copy command.run, delete the logging part (ideally leave only the call to python -m omc3, but you can leave ssh optics2)
• Change outpudir to the new one (otherwise it would overwrite the original, BAD!!!!)
• Change --accel option to lhc instead of LHCB<beam_number>
• Add --lhcmode=lhc_runIII_2023, --beam=<beam_number>
• Change --model to --twiss_file
• Change --tbt_analysis to --algorithm

The file should look like this:

/afs/cern.ch/eng/sl/lintrack/miniconda2/bin/python \
  ../Beta-Beat.src/GetLLM/getsuper.py \
  --accel=lhc \
  --lhcmode=lhc_runIII_2023 \
