type of `NXinsertion_device` #1376

Open sona-patel opened 7 months ago

sona-patel commented 7 months ago

Hello, I am looking for the place of the wavelength shifter (for eg. 7T-WLS-1 at mySpot beamline of BESSY II).

If we put it up as NXinsertion_device, then what one should have it in type ? Can we put there something that is not undulator or wiggler?

Thank you :-)

An insertion device affects the particle beam. Is that what a wavelength shifter does?

prjemian commented 7 months ago

From your beamline's description, the wavelength shifter is the source, as is an undulator or wiggler insertion device.

The list of types does not yet include wavelength_shifter. Seems like that (or similar) would be a reasonable addition.

It would add to the list here: https://github.com/nexusformat/definitions/blob/4c09c7718c41dc90eb996475efdf1c0d30fb1d5d/base_classes/NXinsertion_device.nxdl.xml#L32-L33

@prjemian thanks!

I will make a PR to add wavelength_shifter into the list above.
