Plasma radiation distribution and radiation loads onto the vessel during transient events in JET

The JET bolometer camera system allows greatly improved tomographic reconstruction of the radiation pattern on a timescale of the order of the typical duration of a Type I ELM period (approximate to 0.1-0.4 ms). The ELM-induced radiation is always higher a ...

The evolution of Ap stars

Pierre North

The many peculiarities of Ap stars (not only chemical ones, but also magnetic field and slow rotation) may vary during the main-sequence evolution of these stars. We review here briefly the evidences found in the last thirty years for such evolution, with ...

Density limits in helium plasmas at JET

Richard Pitts

Recently at JET a pure helium campaign has been performed. The exploration of the density limit in L-mode limiter as well as L-mode and H-mode diverted plasmas was one of the main objectives. In L-mode plasmas the density can be increased until the total r ...

Negatively charged excitons in CdTe-based quantum wells: A time-resolved study

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Victoria Ciulin

Using time-resolved photoluminescence, we have investigated the radiative behavior of neutral and negatively charged excitons in CdTe-based quantum wells. We find that the photoluminescence of negatively charged excitons can be well reproduced by a model o ...

Discovery of kHz quasi-periodic oscillations in the Z source Cygnus X-2

Demetri Psaltis

During observations with the Rossi X-Ray Timing Explorer from 1997 June 31 to July 3 we discovered two simultaneous kHz quasi-periodic oscillations (QPOs) near 500 and 860 Hz in the low-mass X-ray binary and Z source Cygnus X-2. In the X-ray color-color di ...
