Design status of the neutron and gamma-ray diagnostics for the Divertor Tokamak Test facility

This is the authors' abstract. We don't add key points for this paper.

In the frame of the design activities of the Divertor Tokamak Test (DTT) facility the development of a comprehensive set of neutron and gamma-ray diagnostics is on-going in order to enable measurements of: neutron yield, neutron yield rate, neutron emissivity over a poloidal section through the plasma; neutron emission spectrum; runaway electrons induced bremsstrahlung radiation and gamma-ray emission from reactions between fast ions and plasma impurities. The present paper provides an overview of the DTT neutron and gamma-ray diagnostics and describes the present status of their design including main components and interfaces, detector types and performances.
