HPTPC PAPER
- hardware: 1 bar Ar data, new source holders will be ; low light level in sparks seems to not be a problem ; need to measure optical plate scale, can probably be done with spark images; should add RHUL runs to good run list.
- DATA QUALITY CUTS (Atkin)

- - p.5 should also look at runs near operating voltages
- - p.9 consider these tentative until we restrict to operating voltages
- - p.11 cross-check with HGMC and/or Pirani for periods with negative pressure values (Ed & Alexander)
- - Toby will add beam stopper info into Ed's quality cuts, also add moderator info
- - Try to get "beam-is-coming" times from dTOF data
- - Look for beam-scintillator in/out info
- gas mixes

- - will use HGMC for 
- CCD IMAGE ANALYSIS
- - Imperial BSc students are making bias subtracted images, and will look into spark cleaning now

SOFTWARE STATUS (Brailsford)
- Sammy has implemented uTOF data, and dTOF implementation is ongoing
- aiming to have 2 separate event input streams in short term: one for TPC and one for TOFs, and unify them later


FLUX PAPER
- dTOF report (Jones)
https://indico.cern.ch/event/769716/sessions/291922/attachments/1745234/2825259/jones__20181101_dTOF_report.pdf
- - p.6 look for additional ways to measure beam intensity across spill?

AOB
git/Overlreaf status: all set up but still need to look into pay version for better features
