Abstract :
A new silicon vertex detector for the BELLE experiment was installed and its operation has started successfully at the high-luminosity asymmetric energy e + e - collider KEKB in October 2003. This vertex detector provides a larger polar angle acceptance, a more precise vertex resolution and a better radiation tolerance than the previous one. The obtained performances indicate that the SVD2 works reliably as expected. Moreover, a prospective simulation study shows that the SVD2 should work under the coming higher background conditions.
