Scientists

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 propagating in magnetized plasma at frequencies around the electron cyclotron frequency and its harmonics. For current Tokamaks, with a magnetic field strength in the range of 3 to 6 T, this frequency lies in the 100 to 200 GHz range. In this frequency range waves of mm-wavelength propagate freely in vacuum.

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.
