摘要： A seven-channel NaI(Tl) detector array installed on an HT-7 superconducting tokamak has been used to detect the hard X-ray (Ehν>20keV) emitted from the plasma. The physical mechanism of the lower hybrid waves propagating and absorbed in the plasma is investigated by the measurement of hard X-ray radial profile at different discharge parameters.

Abstract: A seven-channel NaI(Tl) detector array installed on an HT-7 superconducting tokamak has been used to detect the hard X-ray ($E_{h\nu}>20$keV) emitted from the plasma. The physical mechanism of the lower hybrid waves propagating and absorbed in the plasma is investigated by the measurement of hard X-ray radial profile at different discharge parameters.

Key words: hard X-ray, low hybrid waves, NaI (Tl) detector
