Pion LT Software Meetings

Pion LT software meetings. Please add your talk to the meeting ahead of time. Add the newest meeting to the top of the list!
----

2021.04.26 PionLT Software Meeting

  • Nathan, Heep discussion
    • SHMS can match HMS settings OK
    • No less than 2 degrees between different singles settings ideally, had some settings closer than this, check delta, is it within pm 8%?
      • Can probably overlap many existing (close in angle) settings with 1 new setting
      • Acceptance covers many settings with adequate stats
    • Need to incorporate some runs with the same angle, but at multiple beam energies
  • Jacob, processing various settings too
  • To come from Junaid/Jacob/Nathan - One sheet of proposed settings for each beam energy, Garth will compile
  • Jacob confirmed new matrix elements for HMS are only for 7.59 GeV/c

2021.04.19 PionLT Software Meeting

  • Nathan Presented his Selections for Heep data
  • Stephen showed and discussed new RFtime hcana class and new MM calculations added to THcSecondaryKine
    • Both in and working, MM calculation still be tested a little
    • Pushed to JLab repo
  • Discussion of remote counting house, still going ahead?
    • Info given from Brad, but not progressed much further yet (due to financial constraints fitting it into the previous FY)
    • Garth going to inquire further

2021.04.12 PionLT Software Meeting

  • Discussed HeeP studies further, including event requirements
    • Clarified that 10k events is the lower limit for singles
    • 50k events for coin runs
  • Need to tweak all DEF-cuts files, want All Events, can cut out EDTM manually after as needed
    • Carlos wants to use EDTM events so can't remove them
    • Ali will need to tweak some cuts accordingly to include a removal of the EDTM events
  • Stephen highlighted that HeeP physics analysis scripts are in major need of a refresh
    • Still using old TProof based method, should switch to Python
    • Need more robust file checking/finding in script too
  • Garth highlighted that Peter Bosted had made it very clear that the Physics settings where the current was varied were incredibly useful
    • Want to try working some runs like this into the upcoming run plan
    • Allow us to check FADC efficiencies as fn of rate/current

2021.04.05 PionLT Software Meeting

  • I (Stephen) wasn't there so some minutes would be nice!

2021.03.29 PionLT Software Meeting

  • Jacob updated on HeeP studies
    • Fixed rate issues seen previously
    • Still seeing odd results, can't reconstruct earlier rates
      • Factor ~10 out, probably some odd units?
  • Carlos clarified issues Stephen was having with new Helicity stuff in the replay
  • Vijay suggested switching to Etottracknorm in some Physics analysis (and including it in the DEF-files)
    • Should definitely be kept, doesn't make a huge difference for low level analysis though
      • Working this into scripts will take a little bit of work, can update it as we go along
    • Also including Aero X/Y in all DEF-files now too

2021.03.22 PionLT Software Meeting

  • Casey reported that he had managed to get hcana to compile with root 6.18.00
    • Stephen mentioned he'd had some conflicts with 6.18.04 - will test 6.18.00 too
  • Jacob seeing some replayed files with streamer info missing errors
    • Stephen mentions this is likely just an incomplete or failed replay, if it keeps happening though more info will be needed
  • Casey reported on some more updates to his timing window scripts
    • Now work with HMS windows too
    • Mentioned that Bill Henry is looking at some potentially useful pulse amp plots, useful for other detectors
    • Pulse int vs timing windows for different detectors and other plots
  • Stephen gave an overview of upcoming software tasks
    • Big item on the near horizon is the upcoming second replay of the kaon data, not independent of the pion software work!
      • Need updated report files, new efficiencies in the file, new information in the file
      • DEF-Files still need updating and cleaning, what can we trim out?
      • Which trees do we actually need in each type of replay
      • Which types of events should we actually specify -> ALL_Events vs ALL_Events_No_EDTM issue Richard saw recently
      • Helicity scalers included now too
      • Want to cross check electronic live time multiple ways
    • A point was raised that we should aim to verify selection cutting in the DEF files yields the same result as post processing the replays with the "same" cuts
    • Carlos pointed out that we need to be sure to compare the exact same value in our report files and in our data
    • Casey requested calibration replay and shell scripts
      • Stephen forwarded these on
    • SHMS Calibration code was not in latest hallc_replay repository
      • Casey mentioned Bill Henry hasn't merged it yet, some work is apparently still on going
      • Casey is going to follow up on this with Bill as he had some other items to discuss with him too
    • SIMC comparisons were raised
      • Not quite there yet in our analysis, will be coming very soon (within next month or two) though
      • Garth mentioned he has a slightly different SIMC branch with different generators available
    • Need to make sure updates to kaon analysis feed into the pion analysis and vice versa
  • Garth showed and discussed the latest beam schedule
    • Long beamtime for PionLT this year
    • Final part of experiment actually expected to run next year (2022)
    • Going to be a busy year or two!

2021.03.15 PionLT Software Meeting

  • Replay and Python script running discussion
    • Git changes, new branch for hallc_replay_lt/UTIL_PION/UTIL_BATCH - offline_pionlt
      • Need to modify repo setup script, some issues if branch doesn't exist
      • Will add instructions on how to get and update new branch
      • Will also modify so it automatically checks if the branch exists and gets it if not
    • Pathing changes for c-pionlt and directory structure now all done, working well
    • Some issues with replay scripts, both related to hcana updates
      • How the pcal_geom file is read in has been changed, variable needs to be VAL, VAL and not VAL VAL (comma instead of space) now
      • Helicity stuff no longer working, needed to be commented out for scripts to run
      • Carlos mentioned there's a new map for this, will need to update from hallc_replay
    • Garth raised that Brad was potentially working on an improved GUI for checking online EDTM rates
      • Double check/follow up on this?
    • Discussion of analysis scripts in more detail
      • How the MM is calculated, discussed adjusted values
      • How CT is calculated for each particle species
      • How RF time is utilised in PID
      • Vijay showed RF vs delta and RF vs MM plots and how these can be utilised in PID - RFvDelta, RFvMM, both with Kaon PID cuts applied
      • Stephen will send on some documentation on these topics to Jacob/Julie
    • To do list for software
      • Update hallc_replat_lt with hallc_reply maps
      • Install new hcana in c_kaonlt area
      • Push all hallc_replay_lt fixes
      • Update git script, add instructions

2021.03.08 PionLT Software Meeting

    • Discussed minimal criteria for singles runs
      • No setting shorter than 12 minutes
      • No setting longer than one hour
      • No setting with less than 10k events
      • Want elastics rates of under 100 kHz
    • Criteria/Discussion for coin runs
      • Want roughly 50k elastics
      • Multiple would be good
      • ~3 hours for one previous setting (at 50% data taking eff), this is OK
    • Discussed solid angles for each spectrometer
      • HMS - 8 mSr, 8.1?
      • SHMS - 3.5 mSr, Carlos states > 4 mSr in his thesis
    • Both Nathan and Jacob had some spreadsheets with settings analysed, a few numbers did not match previous settings, both looking into this (probably a solid angle off or similar)
    • Garth sent on Fortran code for cross sections
  • Analysis Code Updates
    • Stephen has finalised the pathing/directory structure updates for
      • hallc_replay_lt
      • UTIL_PION
      • UTIL_BATCH
    • All have a new branch, offline_pionlt
    • Further testing and updates needed, Stephen will work through updating the scripts for the calibrations now that the new structure is set up
      • Some are outdated now, DC, Hodoscopes e.t.c (grab wrong DB files to begin with)
  • Numerous people reported that the farm was very slow over the weekend, if this continues, should raise with Brad/SciComp

2021.03.01 PionLT Software Meeting

  • HeeP studies
    • Students still working on this, Jacob looking at rate calculations
  • Stephen - updates on new git and directory setup scripts
    • Scripts in place but still some work on hallc_replay_lt and UTIL_BATCH needed
      • Issues with pathing that need to be corrected for new area
      • Should have these finalised by mid/late this week
    • Jacob has tested and seems to be working OK
    • Will work on updating/testing DC/Calorimeter calibration scripts next
  • Jacob conducting sanity checks on new matrix elements, noticed discrepancy between kaonlt/pionlt hcana and previous versions, likely due to changes in hcana from April last year
  • Meeting time discussed, remaining at 13:00 ET (which means it shifts to 11:00 Regina time)

2021.02.22 PionLT Software Meeting

      • Thicker aluminium cans, CAD design done but not completely finalised, will know soon
      • KaonLT beamline will be used in 2021 run, new beamline for 2022 run
      • Start of run pushed back slightly, 2022 run will be May to December, PionLT might be slotted into parts of this
    • Stephen
      • Demo2 script fixed, bug was slightly stupid, run not in range but the script did not report this
        • Will look at tweaks to kaonlt.py to fix this
      • New hcana installed in pionlt area, used root 6.14.04, scons issue with newer root (6.18.04)
      • Will create setup scripts for use in migrating over to this area for working
      • Minor issue with /cache/c-pionlt directory, permissions related
  • Discussed plans and potential problems for upcoming run regarding COVID procedures, how many people can be on shift, how many people will travel and so on
  • Will need to shift meeting time in a few weeks due to daylight savings time change for some people

2021.02.15 PionLT Software Meeting

  • Updates from the group
    • Carlos
      • Previously looked at optimisation of kinematics for HeeP data
      • Document on DocDB
      • Will revisit this and try to make some notes on code
    • Stephen
      • No major updates, resolved some issues with scripts Jacob/Junaid were having
      • /group/c-pionlt now exists, will try to install hcana here with a more up to date version of root
      • Garth mentioned some changes to farm software, cmake, singularity, Jupyter - shouldn't affect us much
    • Nathan
      • Combing hodo script DBase files, will try and update, including batch scripts
    • Jacob
      • Sanity checks of running old scripts and comparing to new
      • Should be in place to combine in new matrix elements soon
    • Junaid
      • demo1 being slow, file probably too large
      • Farm also being slow could be an issue
    • Ali
      • Sym link hardcoding, switch location of outputting
  • Idea of a directory setup script, something people can run and it will set up a tree of directories to save files to
    • Can try making a version of this later this week, will need to modify output of lots of scripts!

2021.02.08 PionLT Software Meeting

  • Updates from the group
    • Stephen - Tried to replicate errors Jacob was having with Demo2, could not replicate issues and didn't see any script differences
      • May be a versioning issue, Stephen and Richard will investigate further
      • JLab environment/root version issue likely cause
    • Jacob - Questions about the pionlt directories, all but the /group/c-pionlt one seem to be set up
      • Stephen following up with Brad on this
    • Junaid - Some environment issues
      • Stephen will try to resolve later today
    • Casey - Gave an update on his timing window scripts
  • HeeP running discussion
    • Minimum accessible spectrometer angles - SHMS 5.5, HMS 10.5, opening angle ??
    • Want higher for HeeP running for practicality (no hall access e.t.c.)

2021.02.01 PionLT Software Meeting

  • Updates from the group
    • Stephen - Cointime peak script updates and fixes
    • Jacob - Issues with Demo2 cuts
      • Stephen thinks this may be due to lack of updating of the script after some changes Richard made, will investigate
    • Nathan - Hodoscope script issues, tracked down to .database file. Investigating fixes
    • Junaid - Software setup on Lark but python/root issues here, working on JLab account. Will investigate root compilation on Lark
      • Stephen raised that issue in getting root to compile isn't actually related to the python version used, other package/component causing issues
    • Ali - Working on improving report files and def files
  • Casey Presentation
    • Discussion of process and software used by XEM experiment
    • Nice reference time script in place, will exchange with Stephen/Richard and see what can be merged with each
    • Structure and plan for analysis look similar to our own, will try to collaborate as much as possible on having a nice working set of software for online usage
    • Raised point of online BCM/BPM monitoring
      • Dave mentioned it would be nice to track the stability of the BCM/BPMs over the run period, at least once per shift produce a plot/document checking this
      • Stephen added that this could also track the prescale factors (reported vs calculated)
      • Investigate idea of a once per shift script that checks last X runs and produces plots above

2021.01.25 PionLT Preparation Meeting

2021.01.12 PionLT Software Meeting

  • Stephen Presentation
    • Discussion of analysis tasks and status as of 12/01/21. The non-annotated version of the notes is also available here
    • Homework for next week is the following -
      • Setup and try the batch calibration scripts and the python analysis script demo
      • For Stephen - Check with Brad regarding new area for files
