  • Abstract
    We present the status of the second version of the Silicon Vertex Detector (SVD2) at Belle. SVD2 has been in operation since October 2003, and its innermost layer has accumulated 2.4 kGy of radiation dose. The noise in the inner layers increased by about 20%, while the gain of the readout chips kept stable. In order to cope with the expected luminosity increase of the KEKB collider in the near future, a hardware trigger was upgraded in 2005, resulting in the decrease of the accidental rate while keeping the same trigger hold efficiency. New software is also being implemented to reduce and eliminate background induced hits among the tracking candidates.
