Radiation loss measurements in compact helical system by a metal resistor bolometer

摘要

Radiation loss from compact helical system (CHS) plasma has been detected and approximately measured by a calibrated stainless steel absorber bolometer. The results of the bolometer calibration by two different methods are reported. It has been found that under neutral beam injection heating, about 28.5% of the absorbed power is lost by vacuum ultra-violet (VUV) radiation and charge exchanged neutrals. [References: 11]
