Description:

A spin flipper.

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

Any of these values: coil | current-sheet

flip_turns: (optional) NX_FLOAT {units=NX_PER_LENGTH}

Linear density of turns (such as number of turns/cm) in flipping field coils

comp_turns: (optional) NX_FLOAT {units=NX_PER_LENGTH}

Linear density of turns (such as number of turns/cm) in compensating field coils

guide_turns: (optional) NX_FLOAT {units=NX_PER_LENGTH}

Linear density of turns (such as number of turns/cm) in guide field coils

flip_current: (optional) NX_FLOAT {units=NX_CURRENT}

Flipping field coil current in “on” state”

comp_current: (optional) NX_FLOAT {units=NX_CURRENT}

Compensating field coil current in “on” state”

guide_current: (optional) NX_FLOAT {units=NX_CURRENT}

Guide field coil current in “on” state

thickness: (optional) NX_FLOAT {units=NX_LENGTH}

thickness along path of neutron travel

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
