The BABAR detector

The Babar Detector

BABAR, the detector for the SLAC PEP-II asymmetric e + e − B Factory operating at the Υ (4S) resonance, was designed to allow comprehensive studies of CP-violation in B-meson decays. Charged particle tracks are measured in a multi-layer silicon vertex tracker surrounded by a cylindrical wire drift chamber. Electromagnetic showers from electrons and photons are detected in an array of CsI crysta...

The IFR Online Detector Control system at the BaBar experiment

The Instrumented Flux Return (IFR)[1] is one of the five subdetectors of the BaBar[2] experiment on the PEP II accelerator at SLAC. The IFR consists of 774 Resistive Plate Chamber (RPC) detectors, covering an area of about 2,000 m2 and equipped with 3,000 Front-end Electronic Cards (FEC) reading about 50,000 channels (readout strips). The first aim of a B-factory experiment is to run continuous...

The CsI ( Tl ) Calorimeter of the BaBar Detector

The Asymmetric B-Factory at the Stanford Linear Accelerator Center will study the B-B meson system with focus on CP violation. Its detector BaBar contains a high-resolution CsI(Tl) calorimeter, which is currently under construction. The nal design of the calorimeter (from the crystals to the calibration system) will be presented in this report. Invited talk presented at the 7th International Co...

Local Alignment of the BABAR Silicon Vertex Tracking Detector

The BABAR Silicon Vertex Tracker (SVT) is a five-layer double-sided silicon detector designed to provide precise measurements of the position and direction of primary tracks, and to fully reconstruct low-momentum tracks produced in ee collisions at the PEP-II asymmetric collider at Stanford Linear Accelerator Center. This paper describes the design, implementation, performance, and validation o...
