Abstract Measuring fusion neutron spectra can give essential information on ion fuel ratio and temperature in the plasma core, which are goals of High-Resolution Neutron Spectrometry (HRNS) ITER. At highest powers, this role is foreseen to be fulfilled by a Thin-foil Proton Recoil (TPR) system with ΔE-E silicon detectors. The concept performing TPR spectroscopy Gas Electron Multiplier (GEM), so-called NS-GEM, instead solid-state detectors has recently been proposed [6]. Based simulation...
Abstract The system proposed to measure the tritium deuterium ratio on International Thermonuclear Experimental Reactor (ITER) is a high-resolution neutron spectrometer, partly composed of three Thin-foil Proton Recoil (TPR) spectrometers. This works principle converting neutrons into protons using thin foil polyethylene, which then detected in silicon detectors obtain scattering angles and energy spectrum protons. objective this article show benefit artificial intelligence for improving...
In fusion plasmas, essential plasma parameters can be inferred from x-ray and neutron measurements. The analysis of emitted spectra give access to the fuel ion ratio temperature, while local emissivity contains information about electron magnetic axis, concentration impurities that estimated with help dedicated tomographic inversion synthetic diagnostic tools. We report on ongoing efforts diagnostics tokamak plasmas. A methodology determine core impurity temperature multiple line-integrated...

Different types LiF-based detectors have been used measurements order to evaluate and non-neutron components field channel exposure check their relevancy environment. For high-dose evaluation a new Ultra-High-Temperature Ratio (UHTR) method established highly...
Neutron measurement is considered to be one of the major diagnostic methods in tokamak plasma. The neutron diagnostics provide key information on plasma physics, machine protection and control issues.
