SASsource

Name Type occurrence Description Attributes
radiation string [1..1] Name of the radiation used. For maximum compatibility with NeXus, use one of the names defined by either NeXus NXsource/type
* Spallation Neutron Source
* Pulsed Reactor Neutron Source
* Reactor Neutron Source
* Synchrotron X-ray Source
* Pulsed Muon Source
* Rotating Anode X-ray
* Fixed Tube X-ray
or NeXus NXsource/probe
* neutron
* x-ray
* muon
* electron
beam_size container [0..1] Physical dimension of the beam (incident on the sample). Note: If beam is round, just use X dimension. Note: While Z dimension is allowed by the standard, it does not make sense for small-angle scattering. name="{name}"
beam_shape string [0..1] Text description of the shape of the beam (incident on the sample).
wavelength floating-point number [0..1] wavelength (λ) of radiation incident on the sample. unit="{unit}"
wavelength_min floating-point number [0..1] Some facilities specify wavelength using a range. The minimum of such a range is given by wavelength_min. unit="{unit}"
wavelength_max floating-point number [0..1] Some facilities specify wavelength using a range. The maximum of such a range is given by wavelength_max. unit="{unit}"
wavelength_spread floating-point number [0..1] Some facilities specify the width of the wavelength spectrum. The width of such a range is given by wavelength_spread. unit="{unit}"

Name Type occurrence Description Attributes
x floating-point number [0..1] Dimension of the beam in X.

The unit attribute is required. See cansas1d_documentation#Rules for acceptable values.

unit="{units}"
y floating-point number [0..1] Dimension of the beam in Y.

The unit attribute is required. See cansas1d_documentation#Rules for acceptable values.

unit="{units}"
z floating-point number [0..1] Dimension of the beam in Z.

The unit attribute is required. See cansas1d_documentation#Rules for acceptable values. Note: While Z dimension is allowed by the standard (provided by use of a standard element in the XML Schema), it does not make sense for small-angle scattering.
