1 The Swiss Association vision for the period Presented by M. Q. Tran on behalf of the CRPP

2 Plan Introduction Experimental plasma physics activities : TCV and Torpex Theory and modeling Technology activities in support of ITER and DEMO Conclusion CRPP Contribution Eu Workshop2

3 Introduction The CRPP was founded in May 1961 Since its foundation, it has developed unique expertise in many fields which are of high relevancy for the development of ITER and DEMO The strategy of the Association is to develop these fields along the four lines identified for the programme: 1.Construction of ITER 2.Secure ITER operation 3.Prepare Generation ITER 4.Fusion power plant (DEMO) CRPP Contribution Eu Workshop3

4 The Tokamak à Configuration Variable TCV R= 0.9m; a= 0.25m B T ≤ 1.5T; I p ≤ 1.2MA 16 independent shaping coils 4.5 MW ECW system 1 < elongation < < triangularity < 1 General TCV mission: contribute to physics basis for -ITER scenarios -DEMO design -tokamak concept improvement CRPP Contribution Eu Workshop

5 5 TCV research avenues Advanced scenarios with steady-state internal transport barriers and large non-inductive and bootstrap currents Physics of H-mode, including ELM-free H-mode with X3 Transport, intrinsic rotation and turbulence Physics of Electron Cyclotron Heating and Current Drive Real time control of plasma and heating systems, including new plasma shapes and configurations Plasma edge physics Common aspect: use of TCV unique capabilities (shape, EC, real time capabilities) CRPP Contribution Eu Workshop

6 6 TCV upgrades TCV in operation since 1992, EC heating since 2000 To enhance relevancy of results for burning plasma studies, TCV should achieve –Higher  N, wide range of T e /T i, lower collisionality This would require –Enhancements in heating systems NBI (up to 3x1MW D injectors, E b ~25keV) X3 power upgrade (up to 3x1MW new gyrotrons) –Improvements in plasma control, in particular for ELMs In-vessel RMP coils Modification of in-vessel components (LFS tiles) CRPP Contribution Eu Workshop

7 7 Future role of TCV ITER physics support, scenario development –Wider areas of parameter space, physics of T e /T i variations (including T i ~T e ) with electron heating –Unique input to understand electron-ion coupled turbulence –Move advanced and baseline scenarios into reactor relevant range H-modes with T i ~T e,    >2.5, H 98 >1.5 –Control strategies/validation for sawteeth, NTMs, RWM, ELMs ITER technology support –Control hardware and software Concept improvements (beyond ITER) –New shapes tested in more reactor relevant conditions for stability and confinement (H-mode, , T i /T e ~1) Education –TCV will remain a prolific source of high quality fusion scientists CRPP Contribution Eu Workshop
