Demonstration of viable particle and power exhaust solutions for fusion reactors is the goal of the Divertor Test Tokamak (DTT) facility [1]. Performances and flexibility are the guidelines of the DTT project, in order to test various power exhaust strategies for reactor relevant confined plasmas in a compact device. In this framework, the design and integration of a complex set of diagnostics is being performed taking into account the challenges imposed by advanced performance plasmas, harsh environment and topological constraints. Once identified the scientific and functional requirements of each system, the path towards the realization of the diagnostic components has to address several interface issues, including remote handling compatibility, presence of high magnetic fields, large thermal fluxes, stray electron cyclotron radiation, and severe levels of neutron and gammas radiation, particularly dangerous for optical components and electronics. In addition, a demanding level of integration between the various systems and subsystems imposes the adoption of strict methodologies of functional analysis, to guarantee the multiple functions of plasma control, physics research and machine protection.

Abstract
Demonstration of viable particle and power exhaust solutions for fusion reactors is the goal of the Divertor Test Tokamak (DTT) facility [1]. Performances and flexibility are the guidelines of the DTT project, in order to test various power exhaust strategies for reactor relevant confined plasmas in a compact device. In this framework, the design and integration of a complex set of diagnostics is being performed taking into account the challenges imposed by advanced performance plasmas, harsh environment and topological constraints. Once identified the scientific and functional requirements of each system, the path towards the realization of the diagnostic components has to address several interface issues, including remote handling compatibility, presence of high magnetic fields, large thermal fluxes, stray electron cyclotron radiation, and severe levels of neutron and gammas radiation, particularly dangerous for optical components and electronics. In addition, a demanding level of integration between the various systems and subsystems imposes the adoption of strict methodologies of functional analysis, to guarantee the multiple functions of plasma control, physics research and machine protection.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
