  2. LCIO/Marlin • Decision to use LCIO/Marlin for data storage and processing. • Data will be sent within the DAQ in a simple custom format, and converted to LCIO before being written. • Some issues installing LCIO/Marlin on Mac OS X, but managed to get it working. • Need to define exact format in LCIO

  3. Architecture Key: Application Buffer Thread Signal /data Listening Socket Data Command Logging

  4. DAQ software • Have set up a publicly accessible subversion repository on our server (129.194.52.98, still waiting for a DNS name) • Can be browsed at:http://129.194.52.98/wsvn/eudaq/

  5. Internal Event classes • Base class (Event) and derived classes: • Event(runnumber, triggernumber) • EventTLU(timestamp) • EventRaw(vector[width*height] of pixels) • EventSparse(vector[nhits] of Hit) • Hit(x, y, adc) • Begin/End of Run Events (BORE/EORE)? • All can be serialized and sent over network / to file etc.

  6. GUI • Will always be possible to use command line, but a GUI in addition would also be nice. • Decided to use Qt - easy to use and portable. • Created non-working mock-ups for Run Control and Dummy Producer.
