There is a recording of this meeting. Log into the BlueJeans site first to gain access (use your JLab credentials).

We had a brie meeting.

  • Authorization for Paul to come on-site is in process.
  • Beni will send Paul the coordinates of the PMTs to be replaced.
  • There is a light guide with a broken joint. Performance seems acceptable despite that. Paul may take a look during his visit. Tim and Beni think that first, we should do no harm.
  • We discussed the air light guide test. Tim noted that since the DIRC will not be installed during the coming run, physical interference for de-installation during the run, should that be called for, should not be an issue.
  • FSU is building a remote shift control center in Tallahassee. Many, many computer monitors will be involved.
  • Last week Survey and Alignment re-shot and re-fiducialized the TOF. The results are not back yet.
  • Paul may delay his trip for a week; to be decided.
  • We discussed shots.
