2017-01 recon ver02 plans

Checklist

• New TOF ADC/TDC hit matching (Beni) - check monitoring results
• FCAL
  • Add shower classifier (Matt/Sean) - maybe not at this point
  • Geometry (Sean coordinates) - DONE
  • Update calibrations - three periods: high-rate 2017, low-rate 2017, 2016
    • Gains - DONE for high-rate 2017
    • Shower energy non-linearities - DONE for high-rate 2017
    • Timing:
      • sim-recon - DONE
      • shower time walks - DONE for all 2017
      • block time offsets - DONE for all 2017
• Update Start Counter Resolutions (Mahmoud/Sean) - DONE
• Updates to track projection (Simon) - NOT INCLUDED
• BCAL - charged track reconstruction issues?- Simon - ROLLED BACK TO OLD MATERIAL MAPS
• TAGM - Updates to timing - Alex B./Sean - DONE

Plans

These improvements are expected to go into the next round of reconstructed data:

• improved CDC dE/dx calculation
  • use of ADC amplitude instead of integral - dE/dx vs theta
  • updated truncation value
• improved TOF calibrations
  • use of ADC amplitude instead of integral
• new SC attenuation length corrections
• BCAL charged track clusterizer
• FCAL updates
  • Updated gains (fix problems with inner rings)
  • Updated timing (fix high-rate running problem)
  • Update geometry?
• updated charged/neutral error matrices?

Outstanding questions:

1. What is the bump in BCAL & FCAL monitoring delta T distributions at +4 ns?
   • 
2. What is the bump in SC monitoring delta T distributions at ~ -8 ns?
   • 
3. What is the inefficiency in the TOF matching efficiency near the beam hole due to?
   • 
4. What is going on with the BCAL positions measurements?
