The ZEUS Micro Vertex Detector
During the HERA luminosity shutdown period 2000/01 the tracking system of the ZEUS experiment has been upgraded with a silicon Micro Vertex Detector (MVD). The barrel part of the detector consists of three layers of single sided silicon strip detectors, while the forward section is composed of four wheels. In this report we shortly present the assembly procedure and in more details the test bea...
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 کاملDesign and Tests of the Silicon Sensors for the ZEUS Micro Vertex Detector
To fully exploit the HERA-II upgrade, the ZEUS experiment has installed a Micro Vertex Detector (MVD) using n-type, single-sided, silicon μ-strip sensors with capacitive charge division. The sensors have a readout pitch of 120 μm, with five intermediate strips (20 μm strip pitch). The designs of the silicon sensors and of the test structures used to verify the technological parameters, are pres...
متن کاملBeam Test of Silicon Strip Sensors for the ZEUS Micro Vertex Detector
For the HERA upgrade, the ZEUS experiment has designed and installed a high precision Micro Vertex Detector (MVD) using single sided μ-strip sensors with capacitive charge division. The sensors have a readout pitch of 120 μm, with five intermediate strips (20 μm strip pitch). An extensive test program has been carried out at the DESY-II testbeam facility. In this paper we describe the setup dev...
متن کاملThe Architecture of the ZEUS Micro Vertex Detector DAQ and Second Level Global Track Trigger
The architecture of the ZEUS Micro Vertex Detector data acquisition system and the implementation of its second level trigger, the ZEUS Global Track Trigger are described. Data from the vertex detectors HELIX read-out chips, corresponding to 200k channels, are digitized by 3 crates of ADCs which perform noise and pedestal subtraction, and data suppression and compaction. PowerPC VME board compu...
