FiDeL Data Structure

This system provides model parameters for LSA circuits and Wise magnets in the LHC, with simple data retrieval using a single Oracle table. Input keys include circuit/field order for LSA and magnet/aperture/field order for Wise. Retrieve information based on specific keys combination.

  3. Data Structure Goals • Provide model parameters per circuit for LSA • Requires a knowledge of all circuits (LHC Part ID) • Input keys: circuit + field order (TF or Cn) • Output: input keys + model parameters / keys combination • Provide model parameters per magnet for Wise • Requires a knowledge of all magnets (LHC Part ID) • Input keys: magnet + aperture + field order (TF or Cn) • Output: input keys + model parameters / keys combination • Simple data retrieval • One single Oracle table (if possible) Laurent Deniau - AT/MTM
