Energy dispersion scheme employed, for example: tof, hemispherical, cylindrical, mirror, retarding grid, etc.

pass_energy: (optional) NX_FLOAT {units=NX_ENERGY}

Energy of the electrons on the mean path of the analyser. Pass energy for ...

Energy of the electrons on the mean path of the analyser. Pass energy for hemispherics, drift energy for tofs.

center_energy: (optional) NX_FLOAT {units=NX_ENERGY}

Center of the energy window

energy_interval: (optional) NX_FLOAT {units=NX_ENERGY}

The interval of transmitted energies. It can be two different things depending ...

The interval of transmitted energies. It can be two different things depending on whether the scan is fixed or swept. With a fixed scan it is a 2 vector containing the extrema of the transmitted energy window (smaller number first). With a swept scan of m steps it is a 2xm array of windows one for each measurement point.

diameter: (optional) NX_FLOAT {units=NX_LENGTH}

Diameter of the dispersive orbit

energy_scan_mode: (optional) NX_CHAR

Way of scanning the energy axis (fixed or sweep). ...

Way of scanning the energy axis (fixed or sweep).

Any of these values: fixed | sweep

tof_distance: (optional) NX_FLOAT {units=NX_LENGTH}

Length of the tof drift electrode

APERTURE: (optional) NXaperture

Size, position and shape of a slit in dispersive analyzer, e.g. entrance and ...

Size, position and shape of a slit in dispersive analyzer, e.g. entrance and exit slits.

DEFLECTOR: (optional) NXdeflector

Deflectors in the energy dispersive section

LENS_EM: (optional) NXlens_em

Individual lenses in the energy dispersive section
