•D retention in W co-deposited layers is strongly dependent on the ion energy.•D retention is favored by Ne rather than Ar.•Ne inclusions generate tensile stressed layers.•Ar inclusions generate compressive stressed layers.•nuclear fuel and seeding impurities concentration is almost constant throughout the depth of the co-deposited layers. Deuterium (D) retention in tungsten (W) co-deposited layers, in the presence of neon (Ne) and argon (Ar), was investigated using the bipolar High Power Impulse Magnetron Sputtering (BP-HiPIMS) technique. The deposited layers have a polycrystalline structure, with a preferential growth of W(110) phase. The concentration of D and noble gases (Ne and Ar) is almost constant throughout the depth of the layers. In a D2-Ar discharge, the deposited layers exhibit compressive stress, indicating that Ar is mostly incorporated into the interstitial sites of the W crystal lattice. D retention increases when Ne is added in the discharge, especially when the deposited layer is bombarded with highly energetic ions. Low energy Ne ions (below the W damaging threshold) induce compressive stress, indicating that Ne atoms occupy interstitial sites in the W crystal lattice. High energy Ne ions induce tensile stress, a sign that Ne is trapped in the grain boundaries as inert-gas-vacancy defects, leading to a grain-boundary relaxation. In the presence of Ne, the ion acceleration towards the layer from 0 V to 300 V results in an increase of the D content of about three times, from 3.2 at.% to 8.6 at.%.
