SYSTEM RECORDING X-RADIATION IN INSTALLATIONS OF TOKAMAK TYPE Russian patent published in 2002 - IPC

FIELD: X-ray measurement, identification of small-scale plasma disturbances for analysis of discharge stability and reliable prediction of evolution of plasma collapse in installations of Tokamak type. SUBSTANCE: proposed system comprises collimator, energy filter, radiation detector mounted in vacuum chamber of Tokamak for spatial movement, amplifier, analog-to-digital converter and signal processing system mounted outside of vacuum chamber of Tokamak. X-ray collimator comes in the form of set of mutually perpendicular plates oriented along toroidal angle of vacuum chamber. In addition vacuum chamber houses magnetic sonde connected through additional amplifier and analog-to-digital converter to signal processing system. Vacuum chamber also has hard X-ray sensor connected through additional amplifier and analog-to-digital converter to signal processing system. Technical result of invention consists in possibility of recording of small-scale X-ray oscillations in internal regions of plasma discharge which leads to enhanced authenticity of analysis of plasma stability and makes it feasible to predict evolution of plasma collapse in installations of Tokamak type. EFFECT: enhanced authenticity of analysis of plasma stability. 3 cl, 1 dwg
