ALPHA++ User Guide (version 0.1) [PS] [pdf]

Other userguide-like documents:

• Principles of the ALPHA++ data model, and the concept of AlephVector (now called AlephCollection).
• The various Alpha++ objects are comming from
  • a mapping of the Alpha BOS array,
  • the reconstruction of general information about events
  • and reconstruction of basic physics objects.
• Comparison of ALPHA and ALPHA++ using the main available tools and objects.
• Summary of the ALPHA++ developments till May 2001.
• A full analysis using ALPHA++, and the related presentation.

ALPHA++ is using the following tools: C++, STL, CLHEP, ROOT, LHC++(Anaphe), ALPHA.
