SANS Changes

New Features

  • Added new ANSTO Bilby loader LoadBBY2 for the new Bilby file format that supports time stamped events.

  • Optimized PolarizationCorrectionWildes v1 to reduce computation time by a factor of 4.

  • The option to specify a separate scale factor for the High Angle Bank on compatible instruments (such as LOQ and SANS2D) has been added to the SANS TOML Files.

  • New algorithm DetermineSpinStateOrder v1 which takes a Polarised SANS transmission run and attempts to determine the spin state for each run period.

  • New algorithm SANSISISPolarizationCorrections v1 to calibrate and correct spin leakage in polarized runs for ISIS instruments ZOOM and LARMOR.

  • New algorithm AssertSpinStateOrder v1 which uses DetermineSpinStateOrder v1 to assert the spin state order of a Polarised SANS transmission run. The algorithm can reorder the workspace if the spin state order does not match the expected order.

  • Algorithm HeliumAnalyserEfficiency v1 now accepts multiple transmission runs. It calculates for each one the analyser efficiency and fits the helium polarization. It fits all runs to a decay curve to obtain the lifetime of the analyzer.

  • Added EmptyCellFilename as an optional property of DepolarizedAnalyserTransmission v1 to be used instead of EmptyCellWorkspace. DepolarizedAnalyserTransmission v1 will load the provided file with LoadNexus v1 and then use it the same as EmptyCellWorkspace.

  • New Algorithm HeliumAnalyserEfficiencyTime v1 calculates the efficiency of a helium analyzer at an arbitrary time when given polarization decay parameters: initial polarization, lifetime, and initial or reference time.
