Digital control system for the TCV tokamak

14th IEEE-NPSS Real Time Conference, 2005., 2005
This paper presents the hardware and software approach to replacing the current analogue linear feedback system on the TCV tokamak with a DSP based system to allow for nonlinear control. After preliminary combination, over 120 control signals are reduced to 32 parameters which enter an array of 32 DSP processors each of which is passed the complete ...

DESIGN OF THE TCV TOKAMAK

1991
Various studies have shown that a significant improvement in tokamak performance can be obtained by elongating and shaping the cross section of the plasma ring. Plasmas with high elongation are however strongly unstable to the vertical axisymmetric mode and their control is a major problem.

Current and beta limitations for the TCV tokamak

Nuclear Fusion, 1988
Initial ideal MHD stability results for the Tokamak Configuration Variable (TCV) tokamak with variable elongation are presented. Two configurations have been studied: a racetrack shape and a D-shape at a fixed elongation of 2.5. Low beta studies indicate the existence of stable racetrack equilibria at currents up to an edge safety factor value of qs ...

Power distribution in the snowflake divertor in TCV

Plasma Physics and Controlled Fusion, 2013
TCV experiments demonstrate the basic power exhaust properties of the snowflake (SF) plus and SF minus divertor configurations by measuring the heat fluxes at each of their four divertor legs. The measurements indicate an enhanced transport into the private flux region and a reduction of peak heat fluxes compared to a similar single null configuration.

Recent results from the TCV tokamak

Czechoslovak Journal of Physics, 1995
During the first two years of operation, the TCV tokamak has produced a large variety of plasma shapes and magnetic configurations, with 1.0 less than or equal to B-tor less than or equal to 1.46T, I-p less than or equal to 800kA, kappa less than or equal to 2.05, -0.7 less than or equal to delta less than or equal to 1.

Snowflake divertor experiments on TCV

Plasma Physics and Controlled Fusion, 2010
An ELMy H-mode 'snowflake' (SF) divertor is established and studied for the first time in the TCV tokamak. The H-mode access and the edge localized mode (ELM) dynamics are compared with a conventional single-null diverted configuration. The SF configuration exhibits 15% higher confinement and 2-3 times lower ELM frequency.

Overview of physics research on the TCV tokamak

Nuclear Fusion, 2009
The Tokamak à Configuration Variable (TCV) tokamak is equipped with high-power (4.5 MW), real-time-controllable EC systems and flexible shaping, and plays an important role in fusion research by broadening the parameter range of reactor relevant regimes, by investigating tokamak physics questions and by developing new control tools.
