Several ECE diagnostics are under development as important ingredient of the research program of EAST. HT-7 is equipped with a heterodyne radiometer containing 16 channels and a ECE image system with 8(radial)xl6(vertical) channels. Physical issues including fluctuation by electron and ion modes, low frequency Zonal Flow, magnetic reconnection mechanism, anomalous Doppler resonance effect, etc were investigated on HT-7. These two systems have been moved to EAST after some modifications. New ECE systems including a 32-channel ECE system covering 104?68 GHz and a ECEI system of 24(radial)xl6(vertical) channels are under developing. These two systems are designed to fit the ECH plasma regimes and synergetic work for long range correlation research of plasma turbulence. A grating polychromator ECE system will be installed soon for Te profile measurement covering whole operation range of toroidal magnetic field on EAST. 收起
