scippneutron.conversion.beamline.L1

scippneutron.conversion.beamline.L1(*, incident_beam)

Compute the length of the incident beam.

The result is the primary beam length

\[L_1 = | \mathtt{incident\_beam} |\]

Parameters:

incident_beam (Variable | DataArray | Dataset | DataGroup[Any]) – Beam from source to sample. Expects dtype=vector3.

Returns:

Variable | DataArray | Dataset | DataGroup[Any] – \(L_1\)
