- Abstract
- To experimentally demonstrate the sustainability of the fusion reactions with a Q factor
ranging from 5 to 10 in stationary conditions, the ITER project requires additional heating by
two neutral beam injectors (HNB).
Each HNB will accelerate to 1 MV a 40 A beam of negative deuterons delivering to
the plasma a total power of 33 MW up to one hour. These requirements have never been
experimentally met; hence a strong demonstration activity has been endorsed by ITER to
optimise the crucial components and systems.
A test facility, PRIMA (Padova Research on ITER Megavolt Accelerator), is presently
in the starting phase of construction and procurement at Consorzio RFX (Padova, Italy) in
the CNR research area. The facility requires the construction of new buildings (2 ha) and the
adaptation of the existing 400 kV power substation.
A full-size negative ion source, SPIDER (Source for the Production of Ions of Deuterium
Extracted from Rf plasma), will be operated in the facility to demonstrate the creation
and extraction of a D?/H? current up to 50/60 A on a wide surface (more than 1 m2) with
uniformity within 10 %. The ITER diagnostic beam injector, to be built by the Indian Domestic
Agency, shares some requirements and components with SPIDER and close collaboration
exists. All SPIDER plant systems and components are ready for the procurement phase.
The second experimental device is the prototype of the whole ITER injector, MITICA
(Megavolt ITer Injector and Concept Advancement), aiming to develop the knowledge and the
technologies to guarantee the successful operation of the two injectors to be installed in ITER,
including the capability of 1 MV voltage holding at low pressure. The Japan Domestic Agency
will contribute to the construction of MITICA. Many MITICA plant systems and components
are well developed and close to be ready for procurement.
The experimental effort is supplemented by numerical simulations devoted to the optimisation
of the accelerator optics and to the estimation of heat loads and currents on the
various surfaces. Laboratories, such as KIT-Karlsruhe, IPP-Garching, CCFE-Culham, CEACadarache
and other European research institutions are also cooperating to the success of the
PRIMA enterprise.
In the paper the main requirements will be discussed and the design of the main components
and systems will be described. Finally the status and planning of PRIMA will be
presented.
This work was set up in collaboration and financial support of F4E. (literal)
