NoteThe Dome Liner is one of the parts of the Iter Divertor. The dome is manufactured in tungsten and its function inside the Iter Divertor is to allow radiation and charge exchange neutrals. It also protects the liner and the neutral particle reflector plates from the plasma. The liner protects the cassette body from direct contact of the plasma and allow to exhaust the other impurities.
The dome is manufactured in tungsten, it sees mainly radiation and charge exchange neutrals. It also baffles neutral particles and protects the liner and the neutral particle reflector plates from the plasma. The liner protects the cassette body from direct line of-sight view of the plasma while allowing He and other impurities to be pumped away. He leak test : <1×10-8  mbar. L/s.
