Plasma facing components
The role of
plasma facing components
The components forming the first
wall encountered by the plasma are called "plasma
facing components".
|
These elements receive the thermal
power of the
plasma. In simple terms, this thermal power is lost
from the plasma either :
-
Through radiation
(excitation of impurities, slowing of particles or synchrotron
emission). This power is lost quite uniformly to the first containment
wall. The elements
can easily withstand heat flows of millions of Watts per m² (MW/m²).
-
By heat transport via particles
from the centre of the plasma towards "specialised" equipment around the plasma
(divertor, limiter and so on). This power
is here very localised and the components receiving it should be capable of withstanding heat flows reaching 10 to 20 MW/m² with a surface temperature in the region of 1200°C to 1500°C.

Activities of the EURATOM-CEA Association
The activities of the Association in the field of facing plasma
components are wide ranging, from design, up to manufacture of prototypes with testing in specialised installations.
