The Test Systems area is a fundamental part of the IFMIF-DONES facility since it will be the area where the fusion and non-fusion related experiments will take place.

As general capabilities three planned spaces or experimental areas are currently expected: 1) The Test Cell, 2) the room 160, located just behind the Test Cell (downstream the neutron beam direction) and connected by a neutron line with the Test Cell, and 3) the room 026, underneath the accelerator room.

First, the Test Cell is the special room considered as the core of the facility, inside which, fusion-like neutrons will be produced at the highest fluxes up to 1-5x1014 n/cm2/s [1]. The Test Cell will house the Start Up Monitoring Module that will be used to characterize the neutron flux during the commissioning of the facility. In a later stage, the Test Cell will house the High Flux Test Module which will be located in the highest neutron flux area with the purpose of irradiating the samples of materials (e.g. Eurofer steel) at conditions similar to those expected in DEMO reactor.

Although the current baseline design is mainly focusing on the irradiation of Eurofer inside the HFTM, the possibility of irradiating other materials such as tungsten and copper is also considered upon demand from material science community [2]. In addition, the Test Cell should also potentially provide enough flexibility to incorporate other modules inside it [2] such as Tritium Release Test Module, Creep-Fatigue Test Module among others. Finally, the Test Cell design should also be potentially compatible with the future presence of the two accelerators in the facility (IFMIF configuration).

Second, the room 160 just behind the Test Cell will be provided with neutrons delivered directly from the Test Cell by means of an appropriate neutron beam line penetrating the Test Cell shielding wall plus a neutron beam shutter. Fundamental studies, material and biological sciences, neutron radiography and tomography or radioisotope production for nuclear medicine are some of the activities to be expected in this room [3]. Within the top-level requirements for room 160 is not to interfere with the main experiments conducted in the Test Cell and allow in-person accessibility while Test Cell is in operation.

Third and finally, below the accelerator line, another space is available inside the room 026 that potentially will receive a small fraction of the deuteron beam at 40 MeV to conduct irradiation experiments or to be used for a secondary neutron source, to be designed, covering broad areas of technological and scientific knowledge.
