摘要: An electrostatic dust detector has been successfully developed to measure event in situ and real time on the HT-7 tokamak. For measuring near edge plasmas preventing interference of electrons ions, shielding plates were designed installed around detector. The electric signal measured during LHCD discharges was good agreement with bursts appeared multi-channel H α radiation ECE diagnostics. Diagnostics spectrum measurement impurity emission studied detail. It is interesting that there a delay between CIII line emission. observed about 0.3 ms
