During the 2015-2016 JET campaigns many efforts have been devoted to the exploration of high-performance plasma scenarios envisaged for DT operation in JET. In this paper we review various key recent hybrid discharges and model the combined ICRF+NBI heating. These deuterium discharges with deuterium beams had the ICRF antenna frequency tuned to mat…

"On a fusion born triton effect in JET deuterium discharges with H-minority ICRF heating"

Vasili Kiptily F. Belli J. Eriksson C. Hellesen V.Goloborod’ko K.Schöpf

An effect due to fusion born triton production has been observed in JET high-performance deuterium plasma discharges with NBI and H-minority ICRF heating, using DD and DT neutron spectrometry as well as fusion product loss measurements. The observations show that increase of the triton burn up rate leads to decrease of second harmonic ωcH

"Deuterium density profile determination at JET using a neutron camera and a neutron spectrometer"

J. Eriksson G. Castegnetti S. Conroy G. Ericsson L. Giacomelli C. Hellesen JET-EFDA Contributors

In this work we estimate the fuel ion density profile in deuterium plasmas at JET, using the JET neutron camera, the neutron time-of-flight spectrometer TOFOR, and fusion reactivities modeled by the transport code TRANSP. The framework has been tested using synthetic data, which showed that the density profile could be reconstructed with an average…
