Tokamak Experiment and Diagnostics Division

—　Tokamak Experiment and Diagnostics Division　—

The Tokamak Experiment and Diagnostics Division is devoted to the research on the high temperature plasma physics and diagnostic. As a main research division of the CFS (Center for Fusion Science, SWIP), it has developed more than 30 diagnostic systems since 1970’s. The division is divided into 11 groups, which are the Laser Interferometer Group, the Laser Scattering Group (Thomson scattering and CO₂ laser scattering), the Microwave Group (microwave interferometer, reflectometer and ECE), the Visible Optics Group (infrared TV and Visible CCD), the Charge-Exchange Neutral Particle Analyzer Group, the VUV Group, the X-Ray Group (hard x-ray and soft X-Ray), the Bolometer Group, the Static Electric Probe and Magnetic Probe Group, and the Neutron Detection Group.

The main purposes of the division are
2 To carry on HL-2A experiment ;
2 To process and analyze experiment data;
2 To develop advanced plasma diagnostic systems.
