Specifies the position of the deflector by pointing to the last transformation in the transformation chain in the NXtransformations group.

type: (optional) NX_CHAR

Qualitative type of deflector with respect to the number of pole pieces.

Any of these values: dipole | quadrupole | hexapole | octupole

name: (optional) NX_CHAR

Colloquial or short name for the deflector. For manufacturer names and ...

Colloquial or short name for the deflector. For manufacturer names and identifiers use respective manufacturer fields.

description: (optional) NX_CHAR

voltage: (optional) NX_NUMBER {units=NX_VOLTAGE}

Excitation voltage of the deflector. For dipoles it is a single number. ...

Excitation voltage of the deflector. For dipoles it is a single number. For higher order multipoles, it is an array.

current: (optional) NX_NUMBER {units=NX_CURRENT}

Excitation current of the deflector. For dipoles it is a single number. For higher orders, it is an array.

offset_x: (optional) NX_NUMBER {units=NX_LENGTH}

Spatial offset of the deflector in x direction (perpendicular to ...

Spatial offset of the deflector in x direction (perpendicular to `offset_y`).

offset_y: (optional) NX_NUMBER {units=NX_LENGTH}

Spatial offset of the deflector in y direction (perpendicular to ...

Spatial offset of the deflector in y direction (perpendicular to `offset_x`).

FABRICATION: (optional) NXfabrication

TRANSFORMATIONS: (optional) NXtransformations

Collection of axis-based translations and rotations to describe the location a ...

Collection of axis-based translations and rotations to describe the location and geometry of the deflector as a component in the instrument. Conventions from the NXtransformations base class are used. In principle, the McStas coordinate system is used. The first transformation has to point either to another component of the system or . (for pointing to the reference frame) to relate it relative to the experimental setup. Typically, the components of a system should all be related relative to each other and only one component should relate to the reference coordinate system.
