Abstract
The dummy armour prototypes are identical to the reference components in terms of geometry, cooling circuit and
material except for the armour material, which is replaced by an equivalent thickness of copper alloy. The main
objectives of the dummy armour prototypes are the demonstration of the overall engineering concept of the Divertor,
the integration in a 3° cassette together with components manufactured by the other ITER Home Teams and the
successive thermo – hydraulic tests on the whole Divertor module. This paper describes the realization of both the
wing and the vertical target dummy armour prototypes focusing on the critical aspects of the fabrication and their
impact on a further industrialization of the components. © 2000 Elsevier Science B.V. All rights reserved.

1. Introduction
The EU contribution to the demonstration of
the ITER Divertor includes the design and the
construction of the dummy armour prototypes
(DAP) of both the wing and the vertical target of
the outer channel [1–4]. The DAPs are identical
to the reference components in terms of geometry,
cooling circuit and material except for the armour
material, which is replaced by an equivalent thick-
ness of copper alloy. The aim of the DAPs is the
demonstration of the overall engineering concept
of the divertor, the integration in a 3° cassette
together with components manufactured by the
other ITER home teams and the successive
thermo – hydraulic tests on the whole divertor
module.
This work has been performed in the frame of
the contract NET/96-9083 — outboard ITER
divertor channel medium scale and full scale
mock-ups fabrication.
