Track Reconstruction

Communication

• The Tracking and Charged Particles groups currently operate jointly and have a common weekly meeting
  
  • every Wednesday 10:00 am, SLAC Group C conference room (Bldg 84, B259)
  • call-in: 1-510-665-5437, press 1, enter 123168#
  • meeting announcements (and agendas) are posted in the
