      Review of minutes from the February 27 meeting

We went over the minutes 
<https://halldweb.jlab.org/wiki/index.php/GlueX_TOF_Meeting,_February_27,_2019#Minutes>. 
Thomas will present results from the Machine Learning system he has 
developed for recognizing good and bad TOF monitoring histograms. Ashley 
performed the labeling of the plots.


      Upgrade Plan

Paul gave a comprehensive view of the upgrade plan, including the final 
geometry, design tasks, enumeration of work items, and schedule. See his 
slides on the DocDB 
<https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=3942> 
for the essential ideas. The secretary will not attempt to transcribe 
them here.

 From the discussion:

  * The thinking was that we could do the installation work in July and
    August. That would leave margin before November 1, the nominal start
    of the run.
  * We have enough modules already to accommodate the extra channels
    needed. More cables will have to be fabricated, HV and signal.
    Splitters will also have to be made. Ashley and Beni will go into
    the Hall and confirm this.
  * Total cost is about $50k.
  * Stephanie received STEP files today and will review the design.
  * There are TOF assembly/installation written procedures.
  * Paul would like to have some sort of shelving or storage space for
    the new modules and old modules in the Hall during dis-assembly and
    re-assembly.
  * It would be nice to have a project planning document.
