Hera-b 98{206 Software 98{026 Ranger { a Pattern Recognition Algorithm for the Hera-b Main Tracking System Part Iii: Tracking in the Trigger Chambers
A tracking algorithm based on the Concurrent Track Evolution method has been developed to propagate track candidates which have been found in the main tracking system between vertex detector and RICH into the \trigger chamber" area between RICH and electromagnetic calorimeter. The performance of the method is tested on HERA-B Monte Carlo events with full detector simulation and in the framework of the current software environment.
Hera-b 99{111 Software 99{016 Ranger { a Pattern Recognition Algorithm for the Hera-b Main Tracking System Part V: Compatibility Analysis
The solutions for track reconstruction in the HERA-B main tracking system introduced in previous works 1, 2, 3, 4] have been extended in severals ways. We have analyzed the rate of multiply reconstructed particles and developed and tested a compatibility analysis strategy to suppress such redundancies. We give eeciencies and parameter resolutions after application of this method, where we now also include the silicon strip superlayer SI08, re-evaluate the cpu time requirements on a modern Intel processor and nally show results of rst investigations on an integration of main tracker and vertex detector track segments.
Development and test of a large silicon strip system for a hadron collider Beauty trigger
Abstract Large apecture forward spectrometers with planar geometry perpendicular to the beam line are the natural detectors to accomodate the expected forward peaking of Beauty particle production at high energy hadron colliders. We have designed, built and tested a prototype planar silicon strip vertex detector for triggering such a spectrometer system. The test system consisted of 43 000 channels, configured in six planes, each with four quadrants, perpendicular to the beam line and installed inside the SPS-collider vacuum pipe at the center of an interaction region. Events recorded with the rf shield of the silicon system 1.5 mm from the circulating beams show negligible event-unrelated background.
