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 ...

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.

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.

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.

Overview of TCV results*

Nuclear Fusion, 2008
This overview highlights the progress accomplished on tokamak à configuration variable (TCV) during the past two years, along five research avenues: particle, energy and momentum transport, edge physics, H-mode physics under strong electron heating, electron cyclotron (EC) heating and electron cyclotron current drive physics, scenarios with internal ...

Using APCS for Plasma Vertical Control at TCV

IEEE Transactions on Nuclear Science, 2010
Early tokamaks with circular cross-section plasmas werevertically stable in nature and no problems were reportedon the control of the vertical position. However, theconcept of vertically elongated plasma cross-section,with benefits to the energy confinement time, led tovertical instabilities.

Plasma Shape Control at TCV

2016
A thorough description of the TCV is beyond the scope of this work. The interested reader is referred to [91]. Hereafter, we will outline only those aspects that are relevant to control.
