What is it used for ? Who is responsible for it ? | Bolometers are used for detection of total radiation power losses from plasma. Two arrays of the fast AXUV-20 ELM based bolometers from International Radiation Detectors Inc. were installed on the CASTOR tokamak in mutually perpendicular directions. The first array equipped with 16 channels is placed inside the bottom tokamak port; the second one operating with 19 channels is located at the same poloidal cut and placed inside the horizontal port at low field side (LFS).

Why is it useful ? | The set with unique temporal resolution of 1 µs and spatial resolution about 11 mm or 9 mm allows monitoring of total radiated power and consequently to observe fast changes of radiation losses profile and its relaxation. Additionally, turbulent structures in the edge plasma region are identified. Tomographic reconstruction using Cormacks method is possible. |
