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.
Keywords:  hard X-ray      low hybrid waves      NaI (Tl) detector
