“…In all experiments SRIM has been used in the Kinchin-Pease (KP) mode, to calculate the total fluence needed to reach a certain dpa value [ 26 , 27 , 28 ]. The other parameter needed is the displacement energy of the material [ 16 ] taken from tabulated values [ 8 ], or agreed with the user.…”

The Dual-beam ion irradiation facility for Fusion materials (DiFU) has been developed and installed at the Ruđer Bošković Institute with the purpose to perform irradiation of samples of fusion materials by one or two ion beams. Ion beams are delivered to the DiFU chamber by a 6 MV EN Tandem Van de Graaff and a 1 MV HVE Tandetron accelerator, enabling irradiation of areas up to 30 × 30 mm2. The sample holder enables the three-dimensional positioning of samples that can be irradiated while being heated, cooled, or kept at room temperature. Ion fluxes are measured indirectly by the insertion of two large Faraday cups. Besides, the ion flux is monitored continuously by two sets of horizontal and vertical slits, which, in turn, define the limits of the irradiation area on the sample. Sample temperature and conditions during irradiation are additionally monitored by a set of thermocouples, an IR camera, and a video camera. Particular care is dedicated to the mitigation of carbon contamination during ion irradiation.

“…1 gives the depth-dependent distribution of irradiation dose and injected ion concentration predicted using SRIM-2013 for the 0.37 dpa midrange dose condition. The calculation was performed using the full-cascade mode and damage energy method with the displacement energy of Fe set to 40 eV [43] (the results are com-pared to the Kinchin-Pease Quick Calculation mode in Section 1 of the Supplementary). The analysis region was taken from the mid-range (depth ∼1 μm) as denoted in the figure to minimize the po- tential anomalous contributions from both the surface and injected ions [44].…”

“…Fig. 1 shows the displacement damage profile (in displacements per atom, or dpa) for W ions implanted into W. The data points shown were obtained from SRIM via the so-called Kinchin-Pease "quick" calculation (as recommended in [60,61]). For ion energies of 10, 20 and 50 MeV, the implantation of 10000 W ions were simulated and the resulting vacancies/ion as a function of depth into the sample were used to calculate the dpa for an incident ion fluence of 10 14 ions/cm 2 , which is typical of low-dpa ion-irradiation experiments (see, for example, table S1 in the supplemental material of [25]).…”

Using the notion of eigenstrain produced by the defects formed in a material exposed to high energy neutron irradiation, we develop a method for computing macroscopic elastic stress and strain arising in components of a fusion power plant during operation. In a microstructurally isotropic material, the primary cause of macroscopic elastic stress and strain fields is the spatial variation of neutron exposure. We show that under traction-free boundary conditions, the volume-average elastic stress always vanishes, signifying the formation of a spatially heterogeneous stress state, combining compressive and tensile elastic deformations at different locations in the same component, and resulting solely from the spatial variation of radiation exposure. Several case studies pertinent to the design of a fusion power plant are analysed analytically and numerically, showing that a spatially varying distribution of defects produces significant elastic stresses in ion-irradiated thin films, pressurised cylindrical tubes and breeding blanket modules.
