Vibration measurements of the tokamaks components of TEXTOR and T-10 in operation

Abstract Vibrations and displacements of tokamak components arise during a pulse due to electromagnetic loads. For vibration measurements the sensors and multichannel analogue data acquisition system have been designed and made in the Nuclear Fusion Institute (RRC ‘Kurchatov Institute’). The sensors measure the amplitudes of vibrations in the range of 0.01–10 mm and at band of frequencies up to 1 kHz. The results of vibration measurements of tokamaks components TEXTOR and T-10 are given.
