Status of lsa validation
Status of LSA validation

  • Extracted settings from LSA Injectiontest in 2008.

  • Recently extracted LSA 5 TeV ramp for 2009

  • Initial checking of MB main dipole circuits as used for injection tests in 2008

  • I aim to speed-up my validation (clock ticking)

About lsa data validation
About LSA data validation

  • The LSA generates a table for each circuit current during ramp. The tables has often 100 entries of {t, I} for each circuit

  • A linear interpolation is done for intermediate t.

  • Checking this data size against WISE seems feasible for all circuits rather than to check only a few “snapshots”.

  • Thanks to BE/OP (Marek, Cyril, Grzegorz) for making a new version of the LSA Settings Extractor

  • It dumps data for multiple circuits in “one go”

  • I have used it to dump most of the data I could find inside LSA

Generated warning list for circuits where i op i low
Generated “warning” list for circuits where Iop << Ilow

  • There are some circuits which at injection operates well below the established ILOW

  • It applies mainly to a few normal-conducting magnets with unipolar power supplyExamples: MBW, MBXW Iop ~ 40 A but Ilow=100A

  • MQWB Iop ~ 1 A but missing measurements to characterize below ~ 30 A

  • List given to Marco
