      Review of minutes from the December 5 meeting

We went over the minutes from last time 
<https://halldweb.jlab.org/wiki/index.php/GlueX_TOF_Meeting,_December_5,_2018#Minutes>. 
See the sections below for the discussion.


      Calibration Status

Since last time Ashley has calibrated the last handful of runs for Fall 
2018. She also resolved the Beni-script-ambiguity issue mentioned last 
time. She urged Beni to commit the new "four file" version of the 
scripts to the GitHub repository.


      Lucite Shield Geometry

After the last meeting Ashley consulted with Thomas on a simulation 
configuration. She will run with a single-particle gun event generator 
using geantinos. Beam background will be turned on and the simulation 
run with and without the Lucite shield. Rates will be compared. Thomas 
had to supply one small tweak to MCwrapper to control the beam current 
setting.


      Upgrade Plan

We looked at Paul's presentation 
<https://halldweb.jlab.org/talks/2018/TOF-Mod-Nov2018.pdf> which came in 
too late to view at the last meeting. He presents an variation on Option 
2 (no new electronic channels) and fleshes out Option 3 (8 more 
electronic channels). Both come with corresponding cost estimates.
