[Halld-cpp] CPP meeting this morning

[David Lawrence]

Hi All,

 Minutes of today’s meeting were posted on the wiki page and are copied below.


Minutes[edit<https://halldweb.jlab.org/wiki/index.php?title=%CE%A0_polarizability_Meeting_Apr_8,_2020&action=edit&section=4>]
Announcements:

  *   GlueX NIM paper nearly complete and should go out within a week

Update on Run

  *   Minimal staff from Physics division doing periodic walk throughs to check on hall and counting house
  *   gluonraid3 had alarm. Part is ordered and will be repaired at next opportunity. No data was lost.

Engineering/Design

  *   Met with Tim and Stephanie last week
  *   Elton showed some screen caps of the CAD design Stephanie was showing during meeting
     *   Looked like no clearance between HV boards on detector right (looking downstream) and darkbox. We'll need at least some clearance (Need to ask Stephanie)
     *   Gas connectors may need elbows to redirect tubes away from darkbox
     *   We should suggest adding cables and gas lines to CAD or at least a keep-out zone

Andrew e+e- simulation

  *   Andrew showed some plots of the acceptance as a function We+e- invariant mass
  *   Some issues still with acceptance being >3 in some regions.
  *   Andrew will send code to David to review with fresh eyes
  *   Next steps will be MVA

Jeopardy

  *   Some discussion of delaying Jeopardy PAC for 1 year due to Corvid-19
  *   Rory communicated to Matt S. that CPP would be ready this summer
  *   We all agreed that it would be better for us to do it this year instead of next year
  *   Rory showed list of preparations including outline of the 10 page document
  *   May hear back within a week about any delay. Will discuss writing assignments and timeline at next CPP meeting
  *   Consensus that we should still try and have Experimental Readiness Review this Fall regardless of Jeopardy schedule

Meeting Time

  *   David asked if meeting time could be moved up one hour to 9am to avoid regular conflicts with various other meetings that seem to get scheduled on Wed. at 10am
  *   Everyone OK with it, (except Andrew who was peer-pressured into agreeing with it)
  *   Next week we will start meeting at 9am on Wed.
