• Steady state: material fatigue, energy storage, HT superconductors
• High ne low Te operation: fusion power, lower divertor loads, better pellet penetration (also more feasible HFS)
• No large ELMs (tbc): erosion, control coils.
• Low or no CD needs: low recirculating power, avoid, possibly, bulky NBIs
• No disruptions: forces, dust generation, runaway jets, safety case: cost
• Current free: no central solenoid, no need for high power control systems & coils
Stellarator as a Reactor: potential advantages
Issues: concept maturity, coil complexity, exhaust solution, impurity accumulation.

Stellarator research at CIEMAT: TJ-II (1998)
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011
TJ-II Helical axis stellarator
The “lithium breakthrough”
TJ-II has produced since its start in 1998 a significant scientific contribution, mainly in the areas of
• Turbulence transport
• Global confinement physics in stellarators, role of magnetic topology
• Plasma wall interaction
• Diagnostics development
• Theory & modelling
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011TJ-II results shown at IAEA FEC 2010 summary report
H-mode discovered 30 years ago, not yet a clear explanation for L-H transition-> threshold (ITER)
Contribution to the understanding of the L-H transition mechanism: suppression of ñ precedes onset of Er shear
If zonal flows important: effect of RMP coils on H threshold?
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011
TJ-II strategy
• Contributions to Tokamak and basic physics derived from the capabilities of TJ-II
• Development of the stellarator concept as a realistic solution for a commercial fusion reactor
• Training, education and mobilization of national resources towards fusion
Small and midsize national devices: • High physics/€€ or training/€€ ratio.• High flexibility and quick reaction time.• Contribute to national support to the EU Fusion Programme
Reducing the programme to the largest machines is not always the most efficient solution.

Stellarator line: Near Future Physics Plans
Progress on stellarator Physics, (in support and complementary to W7X)
• Power & particle exhaust: divertor concept Flux expansion divertors Role of Liquid Li limiters & Li coatings
• Impurity accumulation High density High confinement modes Lithium as plasma facing element (low Z)
• Coil complexity & distance to plasma Relaxing constraints on optimized configurations:
Stability limits (high ) Role of magnetic topology (shear, rationals…)
+ stellarator reactor & power plant studies
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011
The scientific case for a TJ-III device
• W7X provides the most advanced, reactor relevant configuration. TJ-III would take the basic principle of W7X design: reactor relevant 3D optimisation
• Significant step forward in computer & optimisation resources: allowing for engineering parameters (coil geometry and coil plasma clearance) to be part of the optimization loop
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011
- Release constraints on stability requirements, magnetic shear and bootstrap current
- Introduce simplified turbulent transport simulations in the optimisation (or full simulations, EUTERPE-like in selected cases)
- Search for alternative divertor solutions (flux expansion, Liquid Li)
- Establish reactor relevance of a down-scaled experiment
• Not a long pulse device (copper coils), size similar to TJ-II
• Using existing building, power supplies and some aux. systems cost could be kept in the order of ~ 50M€
The quest for TJ-III
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011
The quest for TJ-III
• Stellarator Optimization based on NC, Mercier and Ballooning stability.
• Use of Grid computing (Fusion VO): Huge computing power.
• Distributed Asynchronous Bee algorithm: Evolutionary algorithm that explores the phase space (like bees in nature).
• Example of optimzed 3 period compact shearless quasi-isodynamic stellarator.
• Mercier and Ballooning stable
• NC transport at the level of quasi-symmetric device.

Filling the gap until the first IFMIF results
Optimistic scenario: start >2015, finish >2022, first full power irradiations >2024, first irradiation results > 2026
How to progress during the next 15 years with the effects of irradiation:
• Activation
• Dpa´s
• H & He generation
Could be tested with existing fission sources: known Eurofer properties
Very important for mechanical behaviour
Combined effect: requires high energy neutrons (14 Mev). Could simulation only do the job?
Effect can be simulated with accelerators (triple beam)• Same species ( i.e. Fe ) for the dpa´s • He and H beams for implanting the gas
Spanish Programme Strategy EU Fusion Roadmap Workshop, Garching 13.04.2011
MIRIAM – Triple beam ion irradiation facility
• Advantages:
Low activation experiment
Adjustable He/dpa and H/dpa ratio
Adjustable wide range of dpa rate
One irradiation takes 2 weeks (comp. with 2 years on IFMIF)
• Disadvantages
Limited range: 20-25 microns depth (but at least a few grains of most of materials of interest)
(MIRIAM: tens of microns –one order of magnitude higher than any other triple beam facility and «quasi-volumetric»)
Mission: • Maximize the possibilities that the first batch of IFMIF tests has the right material• Try to discover early enough any surprises which might arise with our reference materials • Provide experimental validation for multiscale modelling

TechnoFusion: 2010 highlights and present status
• Pre-engineering design of main buildings finished
• Starting engineering design of complex systems (Triple beam and plasma wall facilities) including validation experiments
Present situation:- Recently established the legal consortium structure to launch the projectBudget: Due to constrains in the financial situation the budget for 2011-12 will be around 3-5 M€ (total)- We need to define in more detail the priorities and to start the acquisition of some equipment as well as the engineering design of complex components
