ITER Diagnostics Group
ITER bolometry: The bolometers measure the total power radiated by the plasma in a wide wavelength range. Using multiple lines of sight and applying algorithms for tomographic reconstruction the spatial distribution of the source of the radiation can be determined.
ITER pressure gauges: This diagnostic measures the neutral gas pressure in multiple locations in the divertor, main chamber and the pump ducts. It is needed both for scientific investigations as well as plasma control.
Both diagnostics are based on designs developed and patented by IPP since the 1980s for ASDEX and ASDEX Upgrade. Ever since further development has continued.
