Basic requirements

• Maintain operational status while
• Improving realism of material and digitization
• Restructuring (package-izing) code
• Moving all constants to parameter files
• Introducing a reconstruction architecture
• Probably Gaudi
• Introducing a data architecture
• probably transient/persistent
• ROOT trees for binary persistenceif so, RIO is
  candidate
• Have new structure in place for first-round Mock
  Data Challenge, and/or a new round of background
  rejection studies
• late summer?

To-do list

• Code Infrastructure
• Parameter handling
• Documentation
• Integrated tests
• Background sources
• Albedo protons (realistic)
• Sky sources
• Simulation
• Nuclear interactions
• Realism
• Energy loss fluctuations
• External geometric description
• Accessed both by Simulation and Reconstruction
• Alignment control
• Enable G4 alternative
• Digitization
• Define as stand-alone module

• Reconstruction
• Latest tracking
• Latest CAL
• Define new architecture
• Data
• Define Persistent service
• Convert IRF to new scheme
• Design Raw data
• Design Event data (recon output)
