NXpolarizer¶
Status:
base class, extends NXobject
Description:
A spin polarizer.
Symbols:
No symbol table
- Groups cited:
Structure:
@default: (optional) NX_CHAR
Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.
type: (optional) NX_CHAR
one of these values: “crystal”, “supermirror”, “3He”
composition: (optional) NX_CHAR
description of the composition of the polarizing material
reflection: (optional) NX_INT (Rank: 1, Dimensions: [3]) {units=NX_UNITLESS}
[hkl] values of nominal reflection
efficiency: (optional) NX_FLOAT {units=NX_DIMENSIONLESS}
polarizing efficiency
depends_on: (optional) NX_CHAR
NeXus positions components by applying a set of translations and rotations to apply to the component starting from 0, 0, 0. The order of these operations is critical and forms what NeXus calls a dependency chain. The depends_on field defines the path to the top most operation of the dependency chain or the string “.” if located in the origin. Usually these operations are stored in a NXtransformations group. But NeXus allows them to be stored anywhere.
TRANSFORMATIONS: (optional) NXtransformations
This is the group recommended for holding the chain of translation and rotation operations necessary to position the component within the instrument. The dependency chain may however traverse similar groups in other component groups.
