New capabilities of the incoherent Thomson scattering diagnostics in the TCV tokamak: divertor and real-time measurements

Basil Duval, Patrick Blanchard, Federico Alberto Alfredo Felici, Xavier Llobet, Joan Decker, Yanis Andrebe, Pierre Lavanchy, Cristian Galperti, Philippe Marmillod, Blaise Marlétaz

This work reports developments of the incoherent TS diagnostic capabilities in the Tokamak a Configuration Variable (TCV). Their goals are to (i) diagnose the TCV divertor region, and (ii) provide Te and ne profiles of the plasma bulk in real-time. These t ...

A Variable Structure Control Scheme Proposal for the Tokamak a Configuration Variable

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Timothy Goodman, Jonathan Graves, Yves Martin, Jean-Marc Moret, Ivo Furno, Duccio Testa

Fusion power is the most significant prospects in the long-term future of energy in the sense that it composes a potentially clean, cheap, and unlimited power source that would substitute the widespread traditional nonrenewable energies, reducing the geogr ...

Thomson scattering measurements in the divertor region of the TCV Tokamak plasmas

Basil Duval, Ivo Furno, Patrick Blanchard, Xavier Llobet, Joan Decker, Yanis Andrebe, Pierre Lavanchy, Riccardo Agnello, Steve Couturier, Severino Antonioni

In order to better study conventional and alternative divertor configurations, the TCV Tokamak was recently upgraded. In-vessel graphite baffles were installed in the TCV chamber to delimit a separate divertor chamber from the core that required enhanced d ...
