Micro Nano-Manuf. 2015;4(1): doi: / Experimental R ex and theoretical R th ratios at 10 Torr. Experimental ratios, shown by the solid symbols, were produced by heating the susceptor stage of the MPCVD reactor. Theoretical ratios, shown by the empty symbols, were produced by use of the CARSFT code. The dashed line connecting the dots illustrates the results from the spline interpolation. Measurements were taken approximately 3 mm above the puck surface. Figure Legend:
