The divertor is a key component for extraction of heat and ash born from the fusion reaction which is the main challenge for the present and future machines. Tungsten with its highest melting point and low hydrogen isotopes retention has been chosen as the material for the ITER divertor withstanding up to 20 MW2/m2.
The Project was signed between CEA, ASIPP and SWIP Institutes on Dec. 2018, the 13th, aiming at establishing cooperative activities among SIFFER members with the realization, installation and scientific and technical exploitation of the actively cooled WEST divertor, covering especially:
- Plasma facing components (PFC) including production and qualification of ITER-like component, development of innovative fusion plasma facing components/materials, etc.,
- Diagnostics of common interest,
- Plasma operation (plasma wall interaction, PFC ageing under ITER relevant large incident particle fluence combined with steady state / transient heat loads, etc.).
