Double-beam facility

The design of a new triple ion beam facility for fusion technology application and studies are in progress at Laboratorio Nacional de Fusion, CIEMAT, Madrid, Spain. The first phase of this facility consists in a double beam linear accelerator system of light ions (H+, D+ up to 12 MeV and He++ up to 15 MeV), impinging in targets relevant for fusion studies, mostly made of lithium compounds. A large number of neutrons will be produced, resulting in radiological hazards.

Advanced nuclear analysis is required for the design of this kind of facilities to evaluate the radiation fields for radioprotection purposes. The work performed by TECF3IR is focused on the design of the radiological shields required for a safe operation of the facility. Dose maps to define the radiological zones of the facility have been produced.
