New developments in double sided silicon strip detectors
1990
A new type of double-sided silicon strip detector has been built and tested using high-density VLSI readout electronics connected to both sides. Capacitive coupling of the strips to the readout electronics has been achieved by integrating the capacitors into the detector design, which was made possible by introducing a new detector biasing concept. Schemes to simplify the technology of the fabrication of the detectors are discussed. The static performance properties of the devices as well as implications of the sue of VLSI electronics in their readout are described. Prototype detectors of the described design equipped with high-density readout electronics have been installed in the ALEPH detector at LEP (Large Electron Positron Collider). Test results on the performance are given. >
