RADIATION BEHAVIOUR DURING ADDITIONAL HEATING OF JET PLASMAS
Additional heating in JET with ICRH or NBI leads to an increase of the total radiated power. This is partly due to the density increase caused by the applied heating method. The relative power loss P-rad/P-tot reaches higher values with RF heating. The density increase can be partly controlled when the plasma is attached to the inner wall. Radiation sources at the plasma edge lead to asymmetric radiation flux profiles. For this case the local emissivities can be derived from the bolometer measurement by a tomographic reconstruction method. Reliable values for the central radiation can be evaluated from the soft X-ray diagnostic when measuring with a 4.4 mu Be filter.
