SYSTEM FOR MEASURING ENERGY DISTRIBUTION OF PLASMA-ESCAPING ATOMS IN TOKAMAK PLANTS Russian patent published in 2007 - IPC G01T1/36 

FIELD: plasma diagnostics.

SUBSTANCE: proposed system characterized in minimized amount of sophisticated pieces of equipment disposed in vacuum and high-radioactivity level areas and in that it can be used, for instance, to measure energy distribution of hydrogen, deuterium, and tritium atoms occurring in tokamak plant plasma (for instance, as result of recharging or recombination) at a time has multichannel collimator, atom peeling foil, scintillation screen in the form of substrate covered with scintillator layer and optically coupled with coordinate-sensing detector by means of optical system affording image transfer, and recording equipment. Scintillation screen can be made of concave shape with its concavity facing beams of ions produced in the course of peeling atoms. This system incorporates provision for simultaneous measurement of atom energy distribution in more than one plasma spatial areas.

EFFECT: enlarged functional capabilities, enhanced reliability and measurement accuracy, ability of eliminating magnetic field distortions in system detrimental to plasma parameters.
