METHOD FOR MEASURING DIRECTION OF MAGNETIC FIELD IN VACUUM PLANTS Russian patent published in 2006 - IPC G01R33/02 

FIELD: technology for non-contact measurement of magnetic field direction in vacuum plants with large volume, in particular, in thermo-nuclear synthesis reactors of tokamak type.

SUBSTANCE: in accordance to method, a beam of atoms is injected into volume, containing plasma in form of plasma wire and acting as a target for aforementioned beam, for producing elementary ions as a result of interaction of atoms of beam with target, while axis of beam crosses axis of plasma wire at straight angle, with following recharging of atomic ions into atoms, and detector is utilized to measure primary direction of atomic output, formed as a result of recharging of atomic ions, on basis of which magnetic field direction is evaluated. A beam of atoms of hydrogen or inert gases can be utilized with energy 1 keV - 300 keV. Primary direction of atoms output can be measured by one or several collimated semiconductor detectors.

EFFECT: improved precision, spatial and temporal resolution of measurements.
