The OPAL Silicon Strip Microvertex Detector with Two Coordinate Readout
The OPAL experiment at the CERN LEP collider recently upgraded its silicon strip microvertex detector from one coordinate readout ( only) to two coordinate readout ( and z). This allows three dimensional vertex reconstruction and should improve lifetime measurements as well as b quark jet identi cation. This paper describes the new microvertex detector system with emphasis on the novel techniqu...
متن کاملCluster Repairing in the Microvertex Detector
The cluster xing algorithms are described for the DELPHI microvertex detector. For the few percent of aaected clusters a considerable improvement in precision and in the description of their resolution function has been obtained.
متن کاملThe Optical Alignment System of the ZEUS MicroVertex Detector
The laser alignment system of the ZEUS microvertex detector is described. The detector was installed in 2001 as part of an upgrade programme in preparation for the second phase of electron-proton physics at the HERA collider. The alignment system monitors the position of the vertex detector support structure with respect to the central tracking detector using semi-transparent amorphous-silicon ...

متن کاملThe Belle Silicon Vertex Detector
The silicon vertex detector of the Belle experiment has been built to provide the vertex information of B meson decays at the KEKB accelerator. It consists of three cylindrical layers of double sided, double metal silicon sensors read out by VA1 chips. The analog signals are transmitted to a system of fast analog-to-digital converters and are reduced on a system based on Motorola Digital Signal...
