The dependence of the proton-triton thermo-nuclear fusion reaction rate on the temperature and total energy content of the high-energy proton distribution function

The endothermic nuclear reaction between thermal tritons and high-energy protons can represent an important contribution to the total neutron yield in tokamak plasmas heated by radio-frequency waves, as the first JET experiments have demonstrated (see Mant ...

Ion temperature fluctuations in ELMy H-mode of the X3 EC-heated plasmas on TCV

Basil Duval, Alexander Karpushov, Christian Schlatter

This paper focuses on interpreting variations in the NPA measured energy distribution of neutral fluxes from the TCV high density H-mode plasma discharges with strong third harmonic electron cyclotron heating (P_{X3}>P_{\Omega}). Two quasi-stationary regim ...

First measurements of oblique ECE with a real-time moveable line-of-sight on TCV

Olivier Sauter, Timothy Goodman, Christian Schlatter, Igor Klimanov

Electron cyclotron (EC) emission (ECE) radiometers viewing perpendicular to the magnetic field are common on nearly all tokamaks for measuring the electron temperature with good spatio-temporal resolution. Two such radiometers are installed on TCV, one loo ...

Reconstruction of ion temperature profiles from single chord NPA measurements on the TCV tokamak

Basil Duval, Alexander Karpushov, Christian Schlatter

The flux of charge exchange ( CX) neutrals measured by neutral particle analysers ( NPAs) is the line integral along the viewline of the NPA and contains information about the ion energy distribution of the observed plasma. On the Tokamaka a Configuration ...

Proton-triton nuclear reaction in ICRF heated plasmas in JET

Duccio Testa, Christian Schlatter

Fast protons can react with tritons in an endothermic nuclear reaction which can act as a source of neutrons in magnetically confined fusion plasmas. We have performed an experiment to systematically study this reaction in low tritium concentration (approx ...

Neutral particle analyzer diagnostics on the TCV tokamak

Basil Duval, Alexander Karpushov, Christian Schlatter

Experimental apparatus and data analysis techniques used in neutral particle analyzer (NPA) diagnostics on the Tokamak a Configuration Variable (TCV) are described. Two NPAs are used on TCV to measure the energy spectrum of neutral particle fluxes from the ...

Error estimation and parameter dependence of the calculation of the fast ion distribution function, temperature, and density using data from the KF1 high energy neutral particle analyzer on Joint European Torus

Duccio Testa, Christian Schlatter

Joint European Torus high energy neutral particle analyzer measures the flux of fast neutrals originating from the plasma core. From this data, the fast ion distribution function f(i)(fast), temperature T-i,perpendicular to(fast), and density n(i)(fast) ar ...
