Fusion for Energy

(European Joint Undertaking for ITER and the Development of Fusion Energy)


Conceptual design and interface specifications of high resolution neutron spectrometer, F4E-GRT-403 (DG)

Project Contractor:

  • Institute of Nuclear Physics Polish Academy of Sciences – Leading Party
  • Uppsala University – Party
  • Italian National Agency for New Technologies, Energy and Sustainable Economic Development, ENEA, Frascati, Italy, Third Party
  • Istituto di Fisica del Plasma “Piero Caldirola” Consiglio Nazionale delle Ricerche, IFP CNR, Milan, Italy, Third Party

The ITER project aims to build a fusion device, twice the size of the largest current devices, with the goal of demonstrating the scientific and technical feasibility of fusion power. It is a joint project between the European Union, China, India, Japan, South Korea, the Russian Federation and the USA. ITER is in construction in Europe, at Cadarache in the south of France. Most of the components that make up the ITER project are to be manufactured by each of the participating countries and contributed in-kind through so-called Domestic Agencies including Fusion for Energy. In many cases the engineering and technologies required to manufacture these components are very advanced.

Fusion reactions are based on either deuterium-deuterium or deuterium-tritium fusion reactions in the plasma producing respectively neutrons of 2.5 and 14 MeV. Neutron measurement systems, called the neutron diagnostics, will be installed on ITER to collect information on the neutron emission from the plasma and to derive a certain number of plasma parameters. The High Resolution Neutron Spectrometer (HRNS) is a part of that ITER neutron diagnostic set.

Diagnostic systems
About 50 individual measurement systems will help to control, evaluate and optimize plasma performance in ITER and to further understanding of plasma physics
