Highlights 2010

&nb

Research proposals should be submitted in a 'standard format' (see end of this page). The facility management will complement each proposal with comments on the feasibility of the required FELIX/FELICE performance, the beam time needed, and other operational aspects. A Programme Advisory Committee convenes two times per year to review requests for beam time, with the aim to set up a priority rating. The rating will be translated into an operation schedule by the facility management.

Electron Cyclotron Waves

Electron cyclotron (EC) waves are electromagnetic oscillations in magnetized plasmas which are characterized by frequencies in the range of the electron cyclotron frequency or its harmonics. The work of the group is concerned with the behavior and usage of EC waves in high temperature fusion plasmas. Typical frequencies are in the 100 GHz range. In this frequency range, the microwaves generally propagate freely from vacuum to well inside the plasma.

The instrumentation development group operatesor is involved in the exploitation of the following diagnostics on the tokamaks TEXTOR, ASDEX-UG and JET.

Multi-Pulse Thomson Scattering

A burst-mode operated 10 kHz TV Thomson scattering system is installed on TEXTOR. The system has a high spatial resolution and can operate with a repetition rate of up to 10 kHz during three bursts of about 5 ms long. Each burst consists of a train of up to 50 pulses with 15 J each. Operation of the laser during one burst has been achieved; operation in a three burst mode is in preparation. Ultra-fast CMOS cameras are used in a Littrow polychromator to detect the Thomson scattered light.

Scientific Programme

The Plasma Diagnostic Group develops high-resolution, ultra-fast multi-channel diagnostics, with the aim to diagnose small-scale structures in hot magnetised plasmas. To stay at the cutting edge, the group pioneers new ideas and technologies.
