On the basis of an assumed impulse-type energy input at auroral oval due to the particle precipitation, the response of the exospheric temperature T ∞ has been investigated in terms of changes in input energy, geomagnetic indices and latitude under

The response of the neutral thermosphere to geomagnetic storms is an important aspect of the study of “space weather”. Yet, this response above the magnetic dip equator has rarely been measured on the dayside because a satellite-borne instrument

For the design of an Accelerator Driven Sub-critical System (ADS), nuclear cross section data are required over a wide energy range for the spallation target and structural materials. The paper summarises the EURATOM RTD Fifth Framework (FP5) Program

A number of experiments with heating of DT plasmas using ICRF waves have been carried out at JET. The results of these experiments have been analysed by comparing experimentally measured quantities with the results of numerical simulations. In partic

In this paper we investigate differences of the ELM behaviour between RF and NB heated H-mode discharges in JET. The main result of this investigation is that the edge pedestal pressure with NB heating is higher than with RF heating for equal power f

Reactor relevant ICRH scenarios have been assessed during DT experiments on the JET tokamak using H mode divertor discharges with ITER-like shapes and safety factors. Deuterium minority heating in tritium plasmas was demonstrated for the first time.

An overview of JET experimental results in DT plasmas directly relevant to ITER modes of operation is presented. Experiments in D:T mixtures varying from 100:0 to 10:90 and those carried out in hydrogen plasmas show that the H mode threshold power ha

Results of experiments investigating the performance of the JET Mark IIA divertor are reported and compared with the performance of its Mark I predecessor. The principal effect of reducing the divertor width (increasing closure) was to increase pumpi
