All-diamond assemblies (top view) with high-quality diamond crystal plates [type IIa, HPHT, (111) surface orientation] mounted on a CVD diamond substrate: (a) assembly with a 300 µm-thick diamond crystal plate mounted using nonperforated CVD diamond springs; (b) assembly with a 100 µm-thick diamond crystal plate mounted using perforated CVD diamond springs; (c) assembly with the same 100 µm-thick diamond crystal plate mounted using nonperforated CVD diamond springs. The bright rectangles in (a)–(c) are the 5 × 2 mm windows in the CVD substrates for passage of X-rays transmitted through the diamond plates. Selected microscope images: (d) an enlarged view of the perforated CVD diamond spring, and (e) a side perspective view of a diamond restrainer. A CVD spring that acts on the HPHT crystal is inserted into a groove in the restrainer. |
