Radiation Resistant High-temperature Bolometer Sensors for Fusion Experiments

Bolometer sensors are used to measure the radiation power in current fusion facilities. The measuring principle is based on the conversion of the incoming electromagnetic radiation into heat. The sensors have to withstand the harsh environmental conditions, especially the high-energy radiation and frequent temperature changes. The two different variants that have been developed employ different base materials and have been tested in initial trials for their suitability for use in modern high-power fusion facilities.
