Plasma blobs in a basic toroidal experiment: Origin, dynamics, and induced transport

Ambrogio Fasoli, Ivo Furno, Benoît Labit, Mario Ludovico Podesta

Detaching plasma blobs with very similar properties to tokamaks are observed in the basic toroidal plasma experiment TORPEX [ A. Fasoli et al., Phys. Plasmas 13, 055902 (2006) ]. The blobs originate from the breaking of wave crests of a drift-interchange w ...

X-mode reflectometry measurements in the JET plasma core region

Duccio Testa

The X-mode radial correlation reflectometry diagnostic on JET has long suffered from strong signal attenuation in the original transmission lines. To reach higher performances, new low-attenuation corrugated circular waveguides and a new cluster of six ant ...

Third-harmonic X-mode, real-time controlled top-launch ECW experiments on TCV Tokamak

Yves Martin, Stefano Alberti, Laurie Porte, Alexander Karpushov, Richard Pitts, Gilles Arnoux, Alessandro Bortolon

In the moderate magneticfield of TCV (1.5T), the recently installed X3 system (3 gyrotrons @118 GHz, 0.45 MW/each, 2s) broadens the operational space with the possibility of heating plasmas at high density, well above the cutoff density of the X2 system (X ...

Implantation and electron emission in cluster-surface collisions

Microscopic processes induced by the controlled deposition of mass selected silver clusters on graphite (HOPG) and Pt(111) are investigated. The implantation of silver clusters into the HOPG surface is analyzed. The first step consists in a systematic stud ...

Synchrotron radiation in radiology: novel X-ray sources

Giorgio Margaritondo, Reto Meuli

X-rays, the key ingredient of radiology, are still primarily produced with the mechanism discovered by Rontgen over one century ago. A different approach, however, is becoming increasingly important: the use of synchrotron sources based on fast-moving elec ...
