Kaon_LT Experiment

h1. 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of Andres's slides on elastic W calculation in hcana - initial issue with negative W values seems to be due to outdated information in standard.kinematics file.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)
