Ion cyclotron resonance heating (ICRH) experiments have been carried out in JET D-T plasmas using scenarios applicable to reactors. Deuterium minority heating in tritium plasmas is used for the first time and produces 1.66 MW of D-T fusion power for an ICR ...
Results from an extensive profile database analysis of JET density profiles in H-mode show that the density peaking factor n(e0)/ < n(e) > in JET H-modes increases as the effective collisionality v(eff) congruent to 10(-14) RZ(eff)n(e)/T-e(2) drops from si ...
Planned experiments in the Joint European Torus [Plasma Physics and Controlled Fusion Research, Proceedings, 13th International Conference, Washington, D.C., 1990 (International Atomic Energy Agency, Vienna, 1991), Vol. 1, p. 27] (JET) with deuterium-triti ...
All major JET systems have been fully commissioned for D-T and the DTE1 series of experiments has started with the D-T fuel mixture and operating conditions foreseen for ITER. In the area of ITER physics, significant results have been produced in both D-D ...
Small specimen test technology (SSTT) has enabled, the development of fusion materials by efficiently using available irradiation volumes. The technology has also evolved in anticipation of the construction and operation of a high-energy neutron source for ...
Due to its pulsed operation mode, a fusion device will have to sustain thermal stresses and at the same time be exposed to a flux of 14 MeV neutrons. In order to simulate this irradiation condition, a new irradiation device has been developed, in which the ...
JET's recent experimental programme proved that 'burning plasma diagnostics', i.e. neutron, alpha particle, He ash, and fuel mixture measurements, can provide very useful information about crucial physical aspects of great reactor relevance. First of all, ...
Two of the methods that can be used for the measurement of the subcriticality of a multiplying system are the inverse kinetic (IK) and the pulsed neutron source (PNS) techniques. These methods depend considerably on correction factors and/or kinetic parame ...
Industry benefits in a number of different ways from the research and technology activities of the European Fusion Programme, overseen by the European Commission. These benefits range from: winning contracts to supply equipment and services to fusion labor ...
Leading long term considerations for choices in the European Long Term Technology programme are the high temperature mechanical- and compatibility properties of structural materials under neutron irradiation. The degrees of fabrication process freedom are ...
