Abstract

Plasma was first obtained successfully on the EAST Tokamak in the autumn of 2006. This was an ohmically heated plasma with rf-assisted pre-ionization for plasma startup. Many diagnostics systems were set up to satisfy the requirement for the description of basic plasma performance. Three hard X-ray detectors have been installed to monitor the runaway electrons with a tangential view into the plasma on the equatorial plane. A BGO (Bi4Ge3O12) scintillator installed in the forward direction was used to detect the hard X-ray emission in the energy range 0.5–7 MeV while two CdTe detectors in the backward and forward directions are used to detect the hard X-ray emission in the energy range 0.3-1.2 MeV. Phenomena observed with these detectors in different discharge conditions are presented here.
