This facility permits ion implantation from 0 up to 60 keV with currents up 150 µA depending on the ion. Particularly helium, hydrogen and duterium has been implanted during the last years making use of this implanter for different tasks related with fusion research. The same implanter staff design and develop different irradiation chambers and experimental set-ups depending on implantation characteristics. The developed experimental systems permit making optical, electrical and desorption experiments in the implanter beam line, in-situ. Particularly simultaneous ionoluminescence and surface electrical conductivity measurements can be made allowing correlation between macroscopic material degradation and defects produced by implnatation.  
This facility permits ion implantation at energies up to 60 keV. For instance, helium, hydrogen and duterium ions have been implanted for a range of studies related with fusion research. The implanter staff have designed and developed different irradiation chambers and experimental set-ups depending on the study requirements. The developed experimental systems permit in-situ optical, electrical and desorption measurements. For instance simultaneous ionoluminescence and surface electrical conductivity measurements can be made thus allowing correlation between macroscopic material degradation and defects produced by implantation.

The facility has been used regularly for metals and insulator work to implant  helium, hydrogen, or deuterium to evaluate microstructural surface degradation, ionoluminescence, surface  electrical degradation and to introduce helium and hydrogen isotopes to perform diffusion and desorption experiments.
 
In-situ measurement capability and expertise.
At this facility different studies on candidate fusion insulators have been carried out, in particular electrical, optical and hydrogen and helium diffusion properties are measured regularly in-situ.  These studies are carried out at controlled temperature, from liquid nitrogen up to 1000 C. Available special irradiation chambers and sample holders have been designed by the implanter staff and fabricated at the Ciemat workshops.
