  42. FiDeL status Luca Bottura • Data collection has advanced at a reduced pace. Data available today covers about 60 % of the magnet families and work is in progress to complete the LHC Magnetic Archive. • The work has focused on: • preparation of the structures for the synthesis of the model parameters (machine layout), • storage of the parameters (database supported by AB-OP), • retrieval and use of the parameters (FiDeL in the LHC controls). • Tracking tests were performed in the benches of SM-18 to verify the accuracy of the model: • 2 dipoles (MB2598, MB2624), • 1 SSS (SSS064), • powered through LSA, implementing the FiDeL algorithm for field forecast and correction, • verified B1 tracking among sectors, B2/B1 tracking among main quadrupoles and dipoles, b3 and b5 correction at each dipole. • Fruitful AT-AB collaboration in the preparation, running and evaluation of the test results LHC software - MAC November 07

  43. FiDeL tracking test results 1/2 The integral dipole field in two MB’s track on average within 1 unit of B1, with peak error of 2.5 units of B1 and reproducibility from cycle to cycle well within1 unit of B1 (including measurement errors !)  1 unit of B1  0.003 units of tune Q The ratio B2/B1 tracks on average within 0.01 unit of tune Q, and the reproducibility from cycle to cycle is within the tolerance window of 0.003 unit of tune (including measurement errors !)

  44. FiDeL tracking test results 2/2 The compensation of the integral b3 in a single dipole, using the FiDeL algorithm, has an error of  0.25 units (quite good !) Integral b3 after compensation Integral b3 before compensation The reproducibility of the b3 compensation, on two MB’s, same powering sequence, is 0.1 units of b3, equivalent to 5 units of chromaticity(excellent!) 10 units of chromaticity  Analysis by N.

  48. DEPLOYMENT AND TESTING

  49. Testing Currently use unit testing (automated black-box testing) for business logic and Data Access Objects GUI applications are tested manually Logic operating on the database  development DB Hardware access  usually on a real hardware (or test FGCs) Goal  setup a testing hardware environment which could be used for a systematic testing (before each release) Lab FGCs, Beam Instrumentation LHC software - MAC November 07
