Mechanical Structure

SVD consists of 8, 10 and 14 ladders in the inner, middle and outer layers, respectively. The total number of full ladders is 32. The ladders are arranged to include some overlap regions in the $r$-$\phi$ plane to help the internal alignment among the sensors. The fraction of the overlap region is 9.7, 3.8, and 8.7 % for the inner, middle, and outer layers, respectively. The ladders are supported by a structure consisting of end rings, support cylinders, and an outer cover, as shown in Fig. [*].
