Action Items

  1. Check with Justin about loading translation table into ccdb. (Beni) Translation has been uploaded to ccdb and checked with a few of the latest data files.
  2. Produce vertex distributions using MC to verify the software is be available for full/empty target commissioning (Andrew)
  3. Check that there is a visual confirmation of target position (Beni/Elton) The Hall D camera on the west end can be used although the focus is not very good. We will need to add a flag to allow visual check of target position.
  4. Ask Mark Dalton to conduct a training of the FCAL dark room for personnel that will adjust the Pb frame. We will find a time when 2-3 CPP persons and FCAL experts can meet with Mark Dalton and Tim for training on positioning of the Pb picture frame absorber.
