Notes from Meeting February 22, 2018¶

• Discussion of Andres's slides on elastic W calculation in hcana - initial issue with negative W values seems to be due to outdated information in standard.kinematics file. Additional investigation ongoing.
  *Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
• Discussion of Richard's slides on run plan kinematics and preparations -
  • everyone agrees that in general want to have as many L/T cross section separations as possible in a robust run plan balancing statistics vs. systematics
  • before actual run may want to do a 3D optimization in all kinematic variables to get the best possible delta(epsilon) for the L/T separations
  • for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
  • kinematics plots W-Q2 show that still need to do some optimization
  • run sheets: include raster size, update coincidence count labeling, and carbon target labeling
• Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.

• Action Items:
  • Post slides/notes from this meeting and procedure to set up hcana in Redmine (Tanja)
  • Update run sheet and kinematic optimization for W/Q2 (Garth)
  • Circulate elastic calculations for kinematic settings (Samip)
  • Continue investigation of elastic data and run plan kinematics (Andres/Richard)
  • Test software installation instructions (Pete)
  • Draft email to JLab management about need for small angle beam pipe - need to have HMS minimum angle of less than 13 degrees for kaon L/T separations (Tanja)

Notes from Meeting March 29, 2018¶

• Luminosity scans (Ryan, Andres, Richard, Pete)
• Macros, SIDIS analysis (Hem, Anashe)
• Elastic data (TBD)
