Status:

base class, extends NXobject

Description:

Partial fluorescence yield (PFY) mode XAS. An energy-dispersive ...

Partial fluorescence yield (PFY) mode XAS. An energy-dispersive detector selects a portion of the fluorescence signal around a chosen emission line:

\[\mu(E) \propto I_f/I_0\]

Symbols:

nEnergy: Number of energy data points

Groups cited:

NXdetector, NXemission_line, NXprocess

Structure:

emission_line: (optional) NXemission_line

The emission line(s) selected in the ROI for the partial ...

The emission line(s) selected in the ROI for the partial fluorescence yield measurement.

i0: (optional) NXdetector

Detector measuring the incident beam intensity ...

Detector measuring the incident beam intensity \(I_0\).

data: (optional) NX_NUMBER (Rank: 1, Dimensions: [nEnergy])

if: (optional) NXdetector

Energy-dispersive fluorescence detector. The ``data`` ...

Energy-dispersive fluorescence detector. The data field holds the fluorescence intensity integrated over the ROI, corrected for dead-time.

data: (optional) NX_NUMBER (Rank: 1, Dimensions: [nEnergy])

dead_time: (optional) NX_FLOAT {units=NX_TIME}

Dead-time correction constant.

live_time: (optional) NX_FLOAT (Rank: 1, Dimensions: [nEnergy]) {units=NX_TIME}

Detector live time per energy point.

PROCESS: (optional) NXprocess

Description of how the intensity was obtained from ...

Description of how the intensity was obtained from the raw detector data (i0, if), including dead-time correction and any self-absorption correction applied.

program: (optional) NX_CHAR

Name of the program used for processing.

version: (optional) NX_CHAR

Version of the program used for processing.

date: (optional) NX_DATE_TIME

Date and time of processing.
