The VUV emission of tungsten in WEST is measured by an absolutely calibrated grazing incidence spectrometer of the Schwob–Fraenkel type, which can scan the lower half of the plasma. We have analysed the detected spectral lines in the range 120–14

The consequences of tungsten (W) melting on divertor lifetime and plasma operation are high priority issues for ITER. Sustained and controlled W-melting experiment has been achieved for the first time in WEST on a poloidal sharp leading edge of an ac

Since the decision to implement a tungsten (W) divertor in ITER, several tokamaks have introduced W in their plasma facing components. For these devices, W monitoring in the core plasma has thus become an important topic of research as its high radia
An extreme ultraviolet spectrometer installed on the Tore Supra tokamak has been calibrated in absolute units of brightness in the range 10-340 Å. This has been performed by means of a combination of techniques. The range 10-113 Å was absolutely ca

Using high-resolution x ray and extreme ultraviolet (EUV) spectrometry, the line emission of W28+ - W50+ ions was measured at the Berlin Electron Beam Ion Trap (EBIT). Our study encompasses a wide range of wavelengths (5-800 A) and includes the obser

Results of cross-section and rate coefficient calculations for electron impact direct and indirect ionization of ions belonging to the GeI isoelectronic sequence (ground 3d104s24p2) are presented. The cross-sections are given at near threshold energi

Dielectronic recombination (DR) rate coefficients are usually calculated employing a low-density coronal model, in which it is assumed that the free electron is captured by an ion in its ground state and that no additional collisional processes occur

The dynamic evolution of plasma columns, generated by a fast capillary discharge setup, was measured by an off-axis imaging apparatus. Appropriate initial conditions were found where stable compression of the plasma column could be obtained. The appe

The radiation from tungsten ions in the extreme ultraviolet spectral region was investigated using a 2-m grazing-incidence spectrometer in conjunction with the Berlin electron beam ion trap. Operating EBIT at beam energies between 900 eV and 1.7 keV
