Report from the Lecce’s Offline Group Rome 6-Feb-2006 The Achievements The People Future Plans

Software Timetable Before Jan. 2004: – A Geant3/Zebra based simulation producing (to different degrees of sophistication) the hits in each of the three subdetectors. – A C++ based program for the simulation and the reconstruction of the data collected with a large prototype of the LXe calorimeter, using the Rome framework – A small number of Kumac macros, running under the Paw environment, for the reconstruction of the showers of the large prototype mentioned in point 2) above.

January 2004 – October 2004 Lecce invited to join Detailed study of MEG software requirements Proposal to MEG Approval by the Collaboration Lecce joined MEG

November 2004 – June 2005 First release of MegRoot (344 classes > 4000 methods) – Framework Architecture derived from AliRoot Data Model: MONARC All Container Classes ready – Fast Simulation: Event Generator for Signal VMC for production of hits – Digitization Naive for Calorimeter and TIC, detailed for Drift Chamber Simulation of waveform from FEE – Reconstruction Pattern Recognition and Kalman Filter in the DC – Interface to RDBMS – Farm Manager Initial studies Software Workshop: Martignano (LE), June 2005

June 2005 – October 2005 Major steering from established plans (collaboration request) – Cancel the plans to migrate the simulation from the fortran into MegRoot – Completely remove the digitization from MegRoot and leave its implementation to the Tokio group, within the Rome framework rather than the MegRoot framework – Implement of the reconstruction and calibration packages for the LXe Prototype October 2005: Milestone met November 2005: MegRoot project cancelled

Leaving MEG Lecce joined upon approval of the Offline Proposal No scientifical reasons for cancelling MegRoot (all milestones were met, adequate manpower was provided) These decisions should be taken collaboration wide

The Offline Group The Splitter Group Total at Lecce: 13.1 FTE

Milestones (from BVR Jul-2005) Test Milestone AssemblyDesignManufactoring Data Challenge Farm Framework Prototype ½ Minifarm Computing Model LPT Analysis Reconstr. Module ½ Minifarm
