NXDL files in the NeXus contributed definitions include propositions from the community for NeXus base classes or application definitions, as well as other NXDL files for long-term archival by NeXus. Consider the contributed definitions as either in *incubation* or a special case not for general use. The :ref:`NIAC` is charged to review any new contributed definitions and provide feedback to the authors before ratification and acceptance as either a base class or application definition. :ref:`NXapm` Atom probe tomography and field-ion microscopy experiments. :ref:`NXcalibration` Draft subclass of NXprocess to describe post-processing calibrations. :ref:`NXchamber` Component of an instrument to store or place objects and specimens. :ref:`NXcollectioncolumn` Draft subclass of NXelectronanalyser to describe the electron collection column of a photoelectron analyser. :ref:`NXcontainer` State of a container holding the sample under investigation. :ref:`NXcorrector_cs` Device for correcting spherical aberrations in an electron microscope. :ref:`NXcsg` constructive solid geometry NeXus class, using :ref:`NXquadric` :ref:`NXcxi_ptycho` Application definition for a ptychography experiment, compatible with CXI from version 1.6. :ref:`NXdeflector` Electro-static deflectors as they are used e.g. in an electron analyser. :ref:`NXdistortion` Draft subclass of NXprocess to describe post-processing distortion correction. :ref:`NXelectronanalyser` Draft subclass of NXinstrument to describe a photoelectron analyser. :ref:`NXelectrostatic_kicker` definition for a electrostatic kicker. :ref:`NXellipsometry` Ellipsometry, complex systems, up to variable angle spectroscopy. :ref:`NXem_nion` (Scanning) transmission electron microscopy with a Nion instrument. :ref:`NXenergydispersion` Draft subclass of NXelectronanalyser to describe the energy dispersion section of a photoelectron analyser. :ref:`NXfib` Set of devices adding focused-ion beam capabilities to an instrument. :ref:`NXion` Set of atoms of a molecular ion or fragment in ToF mass spectrometry. :ref:`NXlens` Draft class definition for electro-static lenses as they are used e.g. in an electron analyser. :ref:`NXlens_em` An electro-magnetic lens. :ref:`NXmagnetic_kicker` definition for a magnetic kicker. :ref:`NXmanipulator` Draft extension of NXpositioner to include fields to describe the use of manipulators in photoemission experiments. :ref:`NXmpes` Most general application definition for multidimensional photoelectron spectroscopy. :ref:`NXmpes_ARPES` This is the most general application definition for multidimensional ARPES. :ref:`NXpeak` Description of peaks, their functional form or measured support. :ref:`NXpulser_apm` Laser-, voltage-, or combined- pulsing to trigger field evaporation. :ref:`NXpump` Device to create reduce an atmosphere to a controlled remaining pressure level. :ref:`NXquadric` definition of a quadric surface. :ref:`NXquadrupole_magnet` definition for a quadrupole magnet. :ref:`NXreflectron` Device for reducing flight time differences of ions in ToF experiments. :ref:`NXregistration` Draft extension of NXobject to include fields to describe image registration procedures. :ref:`NXscanbox_em` Scan unit in an electron microscope which controls the electron beam. :ref:`NXseparator` definition for an electrostatic separator. :ref:`NXsnsevent` This is a definition for event data from Spallation Neutron Source (SNS) at ORNL. :ref:`NXsnshisto` This is a definition for histogram data from Spallation Neutron Source (SNS) at ORNL. :ref:`NXsolenoid_magnet` definition for a solenoid magnet. :ref:`NXsolid_geometry` the head node for constructively defined geometry :ref:`NXspecdata` DEPRECATED: This definition will be removed by 2022. Not for new use. :ref:`NXspin_rotator` definition for a spin rotator. :ref:`NXspindispersion` Draft subclass of NXelectronanalyser to describe the spin filters in photoemission experiments. :ref:`NXstage_lab` Device which holds, aligns, orients, stimulates a specimen. .. toctree:: :hidden: NXapm NXcalibration NXchamber NXcollectioncolumn NXcontainer NXcorrector_cs NXcsg NXcxi_ptycho NXdeflector NXdistortion NXelectronanalyser NXelectrostatic_kicker NXellipsometry NXem_nion NXenergydispersion NXfib NXion NXlens NXlens_em NXmagnetic_kicker NXmanipulator NXmpes NXmpes_ARPES NXpeak NXpulser_apm NXpump NXquadric NXquadrupole_magnet NXreflectron NXregistration NXscanbox_em NXseparator NXsnsevent NXsnshisto NXsolenoid_magnet NXsolid_geometry NXspecdata NXspin_rotator NXspindispersion NXstage_lab
