base class, extends NXobject


Extension of NXpositioner to include fields to describe the use of manipulators in photoemission experiments.


No symbol table

Groups cited:

NXpositioner, NXtransformations


name: (optional) NX_CHAR

Name of the manipulator.

description: (optional) NX_CHAR

A description of the manipulator.

type: (optional) NX_CHAR

Type of manipulator, Hexapod, Rod, etc.

cryocoolant: (optional) NX_BOOLEAN

Is cryocoolant flowing through the manipulator?

cryostat_temperature: (optional) NX_FLOAT {units=NX_TEMPERATURE}

Temperature of the cryostat (coldest point)

heater_power: (optional) NX_FLOAT {units=NX_POWER}

Power in the heater for temperature control.

sample_temperature: (optional) NX_FLOAT {units=NX_TEMPERATURE}

Temperature at the closest point to the sample. This field may also be found in NXsample if present.

drain_current: (optional) NX_FLOAT {units=NX_CURRENT}

Current to neutralize the photoemission current. This field may also be found in NXsample if present.

sample_bias: (optional) NX_FLOAT {units=NX_CURRENT}

Possible bias of the sample with trespect to analyser ground. This field may also be found in NXsample if present.

depends_on: (optional) NX_CHAR

Refers to the last transformation specifying the positon of the manipulator in the NXtransformations chain.

POSITIONER: (optional) NXpositioner

Class to describe the motors that are used in the manipulator

TRANSFORMATIONS: (optional) NXtransformations

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