Аннотация
Co-deposited W-D, W-He, and mixed W-D-He films 250 nm thick were investigated. The films were obtained by magnetron sputtering of W in Ar:D2:He =: 1:1:0, 1:0:1, 1:1:0.05, and 1:1:0.2, gas mixtures and at deposition temperatures of ∼ 350 K, 500 K, and 800 K. The films were studied by thermal desorption spectroscopy (TDS) with Tmax = 2200 K using threshold ionization mass spectrometry to separate D2 and He signals. It was found that films obtained in gas mixtures with mixed He-D2 atmospheres contained less total gas atoms than films deposited in pure D2 or He atmospheres. It was found that in mixed W-D-He films, He trapping with high binding energies (Tdes andgt; 1500 K) is strongly mitigated. © 2022
