Belle II framework and PXD DAQ meeting

21 Feb 2011, 09:00 → 23 Feb 2011, 17:00 Europe/Berlin

Auditorium (MPI fuer Physik)

This meeting covers all technical aspects of the Belle II framework from event generation to simulation/digitization. In addition, the PXD DAQ with its interface to the framework will be discussed.
