H-alpha and Visible Spectroscopy Diagnostic

Customer: Fusion Center, Moscow

The H-alpha and Visible Spectroscopy Diagnostic is one of many diagnostic instruments for monitoring the plasma within the ITER fusion reactor. It measures spectrally, spatially and temporally resolved emission of hydrogen isotopes and impurities, located near the ITER First Wall surface and the diverter.

Design drivers

  • First mirror is exposed to high thermal (inclusive nuclear heating) loads which heats up the first mirror up to 350°C
  • High mechanical loads due to electromagnetic shocks

KTO is responsible for the design and manufacturing of the optical frontend
