What is Technofusion?
Technofusion is the scientific&technical 
installation for fusion research in Spain, 
based on three pillars:
- It is an open facility to European users.
- It is a facility with instrumentation not 
accesible to small research groups.
- It is designed to be closely coordiated with 
the European Fusion Program.
With a budget of 80-100 M€ over five years, 
several top laboratories will be constructed. 
Seven Laboratories
The main technological areas which have been identified 
are: materials and remote handling, with special stress on 
the radiation effects.
Seven Laboratories
Material Irradiation                                       
GOAL: Simulate 
neutron damage
produced in different 
components of a 
reactor
- The effect is simulated by ion 
implantation from 3 accelerators
         2 accelerators for H and He
         1 accelerator for heavy ions
- Tests will be carrie out in 
different materials, evaluating the 
raditation damage, effects in 
magnetic fields...
Thanks to A. Ibarra                    
Seven Laboratories
PLASMA WALL INTERACTION                     
GOAL: Reproduce the high thermal loads to which plasma facing 
materials will be exposed.
Two plasma conditions could be used separately or simultaneously.
To irradiate samples at high powers 
(>10 MW/m2) and high particle fluxes 
(10^24/m2/s) in stationary state.
To irradiate samples using high 
power pulses of short duration (to 
simulate ELM's and disruptions)
Thanks to A. Ibarra                    
Seven Laboratories
CHARACTERIZATION TECHNIQUES         
GOAL: Characterization of fusion materials before, during 
and after radiation and high thermal load expositions
In-situ, ex-situ analisys of physical properties 
(stress, nanoindentation, fluence, fatigue, 
hardness, luminiscence, optical absorption, 
thermal conductivity, difusion, etc...)
Chemical, micro/macro structural analysis: IBA, 
SIMS, APT, TEM+EELS, DRX...
Material processing techniques (FIB, FIB-SEM)
Technical support to other Technofusion 
laboratories
Thanks to A. Ibarra                    
Seven Laboratories
MATERIAL PRODUCTION &PROCESSING
   
GOAL: Fabrication of new materials for fusion in semi-
industrial scale and prototiping level
Advanced processing (mechanical milling, VIM, HIP, SPS, VPS,..) and production                
                 techniques (welding, joining,...)
Mostly metallic materials (ODS stainless steels, nanostructured steels, W alloys,...)
Thanks to A. Ibarra                    
Seven Laboratories
LIQUID METAL TECHNOLOGY                       
   
GOAL: Analysis of 
Technologies associated to 
Liquid Metals used in fusion 
reactors (Li)
- Liquid Li loop for fusion applications            
         VL=4-20 m/s, T= 250-300 ºC
- Free surface experiments, using an 
electron accelerator @ 10 MeV
- Studies of material corrosion under Li flow 
w/o Gamma ray irradiation

Thanks to A. Ibarra                    
Seven Laboratories
REMOTE HANDLING TECHNOLOGY              
GOAL: Development of new robitic techniques compatible 
with the harsh conditions found inside the reactor and 
validation of the current available systems for ITER or IFMIF
Facility for the manipulation of large prototipes (PPD and TBM in ITER and irradiation 
modules in IFMIF)
Room for tests under irradiaction conditions, coupled to an electron accelerator to validate, 
certify and characterization of remote handling tools and instrumentation in an uniform 
ionizing field  equivalent to that of ITER and DEMO and other fusion reactors.
Thanks to A. Ibarra                    
Seven Laboratories
COMPUTATIONAL SIMULATIONS                 
GOAL: Computational 
simulations to support and 
verify experimental results 
obtained in other 
Technofusion Laboratories.
- Computational simulations of components 
for different Technofusion Laboratories and 
ITER, DEMO and IFMIF facilities having into 
account radiation effects.
- Engineering simulations related to fusion 
reactors
- Use of national computational clusters Mare 
Nostrum (Barcelona) and Magerit (UPM)

TECHNOFUSION was initially conceived for magnetic 
confinement fusion needs (ITER, DEMO, IFMIF).
However, can be also used for Inertial Confinement 
Fusion?
THE ANSWER IS YES!
Most of the laboratories are valid for both fusion 
approaches, but for the “plasma wall interaction” 
laboratory since plasmas are fairly different.
