GIF++

• [ ] Understand mixer changes during aging tests
  • [ ] To put Mixer as it was before May
• [ ] GC tests in the elog
  • [ ] To be added with timestamps
• [ ] Check for script analyzing chromatograms
• [ ] Data analysis and cleaning
  • [ ] Find all the HV scans that have wrong configs: for instance, muon beam instead of cosmic muons
  • [ ] Tags for test beam
    • [ ] Script to update config in the db
  • [x] Remove alignment runs from /eos
  • [ ] Remove run folders that are merged
  • [ ] Mark runs where efficiency is not reaching plateau
  • [ ] Check if there are runs in /eos that are not analyzed in the DB
  • [x] Check if there are runs with date mismatching from folder_path date
• [x] Plots to be prepared for aging and test beam. For all the gas mixtures and RPCs
  • [x] Resistivity vs time
  • [x] Ohmic currents vs integrated charge for all
  • [x] Physics currents vs integrated charge
  • [x] Physics - Ohmic current vs integrated charge
  • [x] Ohmic currents vs time
  • [x] Physics currents vs time
  • [x] Physics - Ohmic vs time
  • [x] Muon beam efficiencies for same gas mixture at different test beam (legend to report the integrated charge)
  • [x] Currents vs rate for the same gas mixture and different test beams (legend to report the integrated charge)
  • [x] Currents vs voltage for the source off scans (legend to report integrated charge)
• [ ] Notebook that produces all the plots and stores webpage in https://ghg-studies-eos.web.cern.ch/ghg-studies-eos/ + elog
• [ ] Global check of GIF++ setup
  • [ ] Gas lines
  • [ ] Sampling points
  • [ ] Leak search
  • [ ] P&ID
• [ ] Cabling campaign: in November
• [ ] Resume daily GIF++ checklist
  • [ ] To review the checklist for improvements
• [ ] Bakelite from GT
  • [ ] Check status
  • [ ] Check sizes of RPCs
• [ ] Reorganize folders in rpcgif SWAN

Software

• [ ] Organize the required work for a possible rewrite of the backend of olefin
  • [ ] Understand how to organize gitlab
• [ ] Organize the storage of the data in a new dataframe
  • [ ] For muon signals
  • [ ] For gamma signals
• [ ] Signal level calculations
  • [ ] Simple: simple baseline, time, charge of a peak
  • [ ] To study: advanced baseline calculation
  • [ ] After pulses count
  • [ ] Avalanche and streamer charge integration and separation
  • [ ] Try to calculate charge of each gamma signal
• [ ] Aggregating statistics calculations
  • [ ] calculate features only from central strips
  • [ ] Gamma cluster rate calculations
