Analysis of neutron emission during NBI–ICRF synergistic heating in EAST high neutron rate high discharges

Nuclear Fusion
This paper reports the analysis of neutron emission characteristics in high poloidal beta ( $\beta_{\mathrm{p}}$ ) discharges on the EAST tokamak, where a record fusion neutron rate of $S_{\mathrm{n}} = 3.9 \times 10^{14}$ s $ ^{-1}$ was achieved with ...

Deuterium and tritium density determination at JET using neutron diagnostics

Nuclear Fusion
The fuel ion densities of tritium (T) and deuterium (D) are important parameters for reactor control in fusion experiments. The fuel ion densities typically need to be determined for a wide range of experimental conditions, anywhere between pure ...

Influence of ion cyclotron range of frequencies heating on neutron emission rate in HL-3 tokamak

He jishu
BackgroundIon cyclotron range of frequencies (ICRF) heating is one of the most widely used auxiliary heating methods in tokamaks. The HL-3 tokamak plans to equip a 6 MW ICRF heating system to conduct discharge experiments of high-performance plasma ...

Electromagnetic ion cyclotron waves in the helium branch induced by multiple electromagnetic ion cyclotron triggered emissions

Electromagnetic ion cyclotron waves in the helium branch induced by multiple electromagnetic ion cyclotron triggered emissions
Electromagnetic ion cyclotron (EMIC) triggered emissions with rising tones between the H+ and He+ cyclotron frequencies were found in the inner magnetosphere by the recent Cluster observations. Another type of EMIC wave with a constant frequency is occasionally observed below the He+ cyclotron frequency after the multiple EMIC triggered emissions.

Particle-in-cell simulations of the emission mechanism for fusion product-driven ion cyclotron emission from Tokamak plasmas

, 2009
Self-consistent particle-in-cell (PIC) simulations of fusion born protons in the outer mid-plane edge of JET and TFTR deuterium plasmas illuminate the linear and nonlinear phases of the instability responsible for ion cyclotron emission (ICE) as seen ...
