First wall particle flux measurements in the QUEST spherical tokamak have been conducted, using a permeation probe that employs a first wall candidate ferritic steel alloy F82H as the membrane and also SUS304 as a comparative reference membrane. Permeation measurements have been done during the conditioning steadystate discharges heated with 2.45 GHz and 8.2 GHz ECR. Diffusion and recombination coefficients measured in a laboratory-scale plasma device: VEHICLE-1 are used to interpret the results from the permeation probe measurements in QUEST. These permeation membranes have been analyzed with XPS to evaluate the effects of surface impurities.

“…Pd is a classical hydrogen storage metal which absorbs hydrogen at ambient temperatures and pressures [12]. Pd(core)/Pt(shell) nanoparticles absorb hydrogen at the Pt-Pd interface [13] and pure Pd and Pd-alloys [14] exhibit high activities towards the adsorption and oxidation of hydrogen in alkaline media.…”

“…4) Furthermore, the diffusion of hydrogen in BCC metals is significantly faster than that in FCC and HCP metals. 5) In recent years, many attempts to synthesize Mg-based alloys with a BCC structure have been made and novel MgCo 6,7) and Mg-Tm-V (Tm: transition metals) 8) alloys have been successfully synthesized by means of ball milling. In our previous works, Mg-Ti alloys with a BCC structure have been successfully synthesized by means of ball milling.…”

Effect of Li Addition on Synthesis of Mg-Ti BCC Alloys by means of Ball Milling

The effect of Li addition to Mg on synthesis of Mg-Ti BCC alloys by means of ball milling was studied. Mg-x at%Li (x ¼ 4; 20; 46) alloys prepared by the induction melting method consisted of the HCP phase (Mg-type), the HCP phase + the BCC phase (Li-type) and the BCC phase, respectively. Lattice parameters of the HCP phase decreased with the increase in x, whereas those of the BCC phase at x ¼ 20 and 46 were smaller than that of Li. Mg-x at%Li (x ¼ 4; 20; 46) alloys and Ti were milled for 50-200 h in an argon atmosphere. Formation of Mg 96 Li 4 Ti 100 BCC alloy was confirmed by X-ray diffraction (XRD) measurements after 50 h milling. By Li addition to Mg, the synthesis time of the BCC phase was shortened. Li made Mg deformation facile by the activation of the non-basal slips in Mg, and raw materials were efficiently milled. The crystallite size of Ti was readily reduced and formation of the BCC phase was accelerated. The crystallite size and lattice parameter of Mg 96 Li 4 Ti 100 BCC alloy were similar to those of Mg 100 Ti 100 BCC alloy.
