Indirect Diffraction Testing

Diffraction

Preparation

  • You need access to the ISIS data archive

  • osiris_041_RES10.cal file from the unit test data

Time required 2-5 minutes

  1. Open Interfaces > Indirect > Diffraction

  2. Make sure Instrument is set to IRIS

  3. The default Detector Grouping should be All

  4. In Run Numbers enter 26176

  5. Click Run

  6. The output workspace should have 1 spectra

  7. Change the Detector Grouping to Groups and enter 4 groups

  8. Click Run

  9. The output workspace should have 4 spectra

  10. Change the Detector Grouping to Custom, enter 105-108,109-112

  11. Click Run

  12. The output workspace should have 2 spectra

  13. Still using Custom, try spectra numbers outside of the range 105-112. This should not be allowed.

  14. Using Groups, try more than 8 groups. This should not be allowed.

  15. Using File, try an empty string. This should not be allowed.

Time required 2-5 minutes

  1. Open Interfaces > Indirect > Diffraction

  2. Make sure Instrument is set to OSIRIS

  3. Set Reflection to Diffonly

  4. In Run Numbers enter 89813

  5. In Vanadium File enter 89757

  6. In Cal File load the osiris_041_RES10.cal file from the unit test data

  7. Select Detector Grouping to be All

  8. Click Run

  9. There should be three output workspaces, ending in _dRange, _q and _tof

  10. Each of the output workspaces should have 1 spectra

  11. Change the Detector Grouping to Groups and enter 5 groups

  12. Click Run

  13. Each of the output workspaces should have 5 spectra

  14. Change the Detector Grouping to Custom, enter 3-500,501-962

  15. Click Run

  16. Each of the output workspaces should have 2 spectra
