ess.dream.data.lookup_table_high_flux(bc=215)[source]#

Path to a HDF5 file containing a wavelength lookup table for high-flux mode.

The table was created using the tof package and the chopper settings for the DREAM instrument in high-resolution mode. Can return tables for two different band-control chopper (BC) settings: - bc=215: corresponds to the settings of the choppers in the tutorial data. - bc=240: a setting with less time overlap between frames.

Note that the phase of the band-control chopper (BCC) was set to 215 degrees in the Geant4 simulation which generated the data used in the documentation notebooks. This has since been found to be non-optimal as it leads to time overlap between the two frames, and a value of 240 degrees is now recommended.

This table was computed using Create a wavelength lookup table for DREAM with NumberOfSimulatedNeutrons = 5_000_000.

Parameters:

bc (Literal[215, 240], default: 215) – Band-control chopper (BC) setting. The default is 215, which corresponds to the settings of the choppers in the tutorial data.

Return type:
