2.3.3.2.4. Photoemission & core-level spectroscopy

Introduction

These are a set of application definitions to describe multidimensional photoemission (MPES) experiments including x-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), hard x-ray photoelectron spectroscopy (HAXPES), angle-resolved photoemission spectroscopy (ARPES), two-photon photoemission (2PPE) and photoemission electron microscopy (PEEM). Also includes descriptors for advanced specializations, such as spin-resolution, time resolution, near-ambient pressure conditions, dichroism etc.

Application Definitions

NXmpes

A general application definition with minimalistic metadata requirements, apt to describe all photoemission experiments.

NXmpes_arpes

An application definition for angle-resolved photoemission spectroscopy (ARPES) experiments.

NXxps

An application definition for X-ray/UV photoelectron spectroscopy (XPS/UPS) experiments.

NXarpes

An application definition for angular resolved photo emission spectroscopy. Note that this application definition is only kept for legacy reasons and new NeXus ARPES files should use NXmpes_arpes.

Base classes
