Status:

application definition, extends NXtofraw

Description:

This is a application definition for raw data from a direct geometry TOF spectrometer

Symbols:

No symbol table

Groups cited:

NXdisk_chopper, NXentry, NXfermi_chopper, NXinstrument

Structure:

Official NeXus NXDL schema to which this file conforms

Obligatory value: NXdirecttof

INSTRUMENT: (required) NXinstrument

We definitly want the rotation_speed and energy of the chopper. Thus either a fermi_chopper or a disk_chopper group is required.

fermi_chopper: (optional) NXfermi_chopper

rotation_speed: (required) NX_FLOAT {units=NX_FREQUENCY}

chopper rotation speed

energy: (required) NX_FLOAT {units=NX_ENERGY}

energy selected

disk_chopper: (optional) NXdisk_chopper

rotation_speed: (required) NX_FLOAT {units=NX_FREQUENCY}

chopper rotation speed

energy: (required) NX_FLOAT {units=NX_ENERGY}

energy selected
