摘要: Some recent JET campaigns, with the introduction of a trace amount (nT/nD < 5%) tritium into D plasmas and third harmonic ICRH acceleration 4He, provided unique opportunities to test 'burning plasma' diagnostics. In particular, new approaches techniques were investigated for detection neutrons, α particles fuel mixture. With regard neutron detection, activity covered aspects such as calibration cross validation diagnostics, measurement spatial distribution particle transport spectrometry. The first tests some technologies also undertaken during Trace Tritium Experiment campaign. To improve JET's diagnostic capability in field particles, significant development programme was devoted their confinement imaging γ-ray spectroscopy. A approach fusion community measuring fast ion losses, based on activation technique, attempted time JET. An assessment neutral analyser's potential determine mixture coefficients is under way.
