scippneutron.conversion.tof.wavelength_from_tof(*, tof, Ltotal)[source]#

Compute the wavelength from time-of-flight.

The result is the de Broglie wavelength

$$\lambda =\frac{ht}{m_n{L}_{\mathsf{total}}}$$

Where $m_n$ is the neutron mass and $h$ the Planck constant.

Parameters:

• tof (Variable) – Time-of-flight $t$.

• Ltotal (Variable) – Total beam length.

Returns:

Variable – Wavelength $\lambda$. Has unit ångström.
