Abstract
The main purpose of the Divertor Tokamak Test facility (DTT) [1], whose construction is starting in Frascati,Italy, is to study solutions to mitigate the issue of power exhaust in conditions relevant for ITER and DEMO. DTTwill be equipped with a significant amount of auxiliary heating power (45 MW) to reach PS EP/R=15MWm-1required to be DEMO-relevant [2]. DDT is characterized by high flexibility for the assembling and testing ofdivertor components and for the different magnetic configurations to address the integrated physics and tech-nology problems. The conceptual design of the beamline for the DTT Neutral Beam Heating system is herepresented, with a particular focus on the technical solutions adopted to maximize the RAMI indexes (Reliability,Availability, Maintainability and Inspectability) and minimize complexity and costs. Various design options wereconsidered, and a comprehensive set of simulations was carried out using several physics and engineering codesto drive the choice of the most suitable design options and optimize them, aiming at finding a good compromiseamong different design requirements. This paper describes the design of the main components of the beamline,explaining the motivations for the main design choices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
