Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
X-rays
Electromagnetic radiation with energies in the range of atomic inner core shell binding energies. This energy range starts at energies of about 30 eV (e.g. Li-K or Na-LIII edges), and extends up to several hundred keV.
X-ray tube
Vacuum tube in which electrons hit a target (anode) in order to produce electromagnetic radiation caused by the deceleration of electrons (Bremsstrahlung) or a recombination of inner core holes (characteristic radiation).
{ X-ray radiation generated from plasma (plasma for generation of electrons to be accelerated towards an anode H01J 35/00) }
Definition statement
This subclass/group covers:

Generation of recombination radiation in hot plasma, interaction of laser radiation with highly charged ions for harmonics generation.

Devices in which a plasma is used for generation of electrons to be accelerated towards an anode
{ being produced from a liquid or gas}
Definition statement
This subclass/group covers:

Generation of radiation from plasma being produced from material which is provided in a non-bulk state, including liquids which solidify (in clusters or frozen droplets) in the vacuum chamber, e.g. after passing the liquid through a nozzle; discharge plasma sources;Including Sn or Li sources where the material to be excited is evaporated or molten before excitation to plasma
