Abstract
Using 6.8 fb(-1) of data taken between October 1999 and July 2000, the perf ormance of the silicon vertex detector (SVD) in the BELLE experiment is rev iewed. The main purpose of the SVD is to make precise measurements of the B decay vertex position, which are essential for the observation of CP asymm etries. Excellent vertex resolution and a good detection efficiency are req uired for the SVD. Basic performance parameters such as signal pulse height , noise, strip yield, and intrinsic resolution are reported. The SVD perfor mance parameters that are directly related to physics analysis such as trac k matching efficiency, impact parameter resolution, and vertex resolution a re also shown.
