OVERVIEW

  • Update Since Analysis Meeting Nov, 2017

  • iTPC Software Plan

    • Nov 2017 : Demonstrate first simulations, reconstruction, and evaluation
    • Jan 2018 : Online code ready – to reconstruct real data
    • Feb 2018 : Code evaluation with cosmic data
    • March-May 2018 : Real data evaluation

Scope of the Software

  • Data reconstruction in iTPC era
  • Simulations with new iTPC Geometry
  • Simulation with new iTPC Electonics: ALTRO → SAMPA

Update on the Status : General

  • Software was migrated to dev area
  • Sucessfully tested showing the below results
  • The shown results are based on Agi geometry scheme
  • AgML geometry for complete iTPC is ready and the work for scheme change is in progress

Update on the Status : y2018 issue

  • Defficiency for y2018 recovered

Update on Status : ALTRO → SAMPA

  • SAMPA has four pole digital tail cancellation capability vs. three in ALTRO
  • Forth tail cancellation step added to the software
  • Pulser data from iTPC will be used to select the TCF parameters

Reading Real Data

  • itpc is a new data stream to read out
  • It was added to the software

iTPC Data

  • iTPC sector 20 was tested and pulser signal recorded
  • Data is sucessfully read as shown below

Summary

  • Software sucessfully tested on dev
  • AgML for complete iTPC created and interface conversion in progress
  • New itpc readout added : ready to take data
  • Pulser data will be used to optimize TCF
  • Software discussed with and passed to the S&C group for their review
  • The work with the S&C group continues towards final integration
  • Let the cosmic rays flow through the iTPC...
