A CCD vertex detector for a high-energy linear e+e− Collider

Abstract

I present a summary of the experience with CCD-based vertex detectors at the SLD experiment at SLAC, and discuss their advantages for use at a future highenergy linear e + e − collider. The extensive R&D programme to improve further the vertexing capabilities of CCD detectors is also outlined.

Track detectors

“…Because of the charge coupling of the pads, this type of silicon detector is also called a charge-coupled device. Commercially available CCD detectors with external dimensions of 1 × 1 cm 2 have about 10 5 pixels [35,[106][107][108]. Modern devices in commercial cameras have up to 10 megapixels.…”

Overview of silicon detectors

“…The SLD vertex detector used Charge Couple Devices (CCD) to reconstruct the Z 0 decay products at the SLD [4]. The principle of CCD [5] is to capture charge generated in a 20 mm thick depletion layer in a potential well just below the surface.…”

Overview of silicon detectors

“…A total number of 175,000 electronic channels were used to read out the strips, while 1:2 Â 10 6 pixels were installed for enabling pattern recognition in the limited available space. The total sensitive detector surface was about 1:8 m 2 : The SLD vertex detector used Charge Couple Devices (CCD) to reconstruct the Z 0 decay products at the SLD [4]. The principle of CCD [5] is to capture charge generated in a 20 mm thick depletion layer in a potential well just below the surface.…”
