Minutes of the Jan 22 Background Remediation video meeting

  1. The Background Remediation Workshop Executive Summary prepared by the BR Steering Committee was presented. No changes were deemed necessary. This document was presented by GW to BABAR management on Wednesday Jan 20. They consider very seriously our recommendation about a possible 1 week extension of the February run. A decision will take place this week after review of the machine achievements up to now (Note added since the meeting : BABAR position will have to be announced to SLAC direction on Friday Jan 29. This issue will be discussed during BABAR management meeting scheduled on Thursday Jan 28).
  2. The action items and Open issues were not discussed in detail due to lack of participation of the key persons. GW will assign names to the tasks and the list will be reviewed during the upcoming meetings. In particular, a schedule and milestones will be requested for the important ones.
  3. The parameters important for background-vs-luminosity optimisation were briefly discussed: Number of bunches, current in each bunch, beam-beam effect, optimal ratio of the beam currents. (More details here).
  • It was felt that no urgent action was needed on this point.
