PLASMA TECHNIQUE; PRODUCTION OF ACCELERATED ELECTRICALLY-CHARGED PARTICLES OR OF NEUTRONS; PRODUCTION OR ACCELERATION OF NEUTRAL MOLECULAR OR ATOMIC BEAMS

Introduced: September 1968

Classification Context

Section:
ELECTRICITY
Class:
ELECTRIC TECHNIQUES NOT OTHERWISE PROVIDED FOR
Subclass:
PLASMA TECHNIQUE; PRODUCTION OF ACCELERATED ELECTRICALLY-CHARGED PARTICLES OR OF NEUTRONS; PRODUCTION OR ACCELERATION OF NEUTRAL MOLECULAR OR ATOMIC BEAMS

Description

H05H covers plasma generation and manipulation techniques, along with systems for producing and accelerating charged particles (ions, electrons), neutrons, and neutral atomic/molecular beams. This includes plasma confinement methods, ion sources, particle accelerators, and beam production apparatus used in fusion research, materials processing, medical applications, and scientific instrumentation. The classification encompasses both the technical apparatus and operational methods for generating, controlling, and directing high-energy particle streams, excluding applications already covered by specialized accelerator classes (such as H05C) or general electrical discharge phenomena classified elsewhere.
