STAR Integrated Tracker
A. Rose
Abstract
We present the design and performance analysis of a new integrated track reconstruction code developed for the STAR experiment at RHIC. The code is meant to replace multiple previous tracking codes written in FORTRAN many years ago, and to readily enable the integration of new and varied detector components. The new tracker is written from the ground up in C++ using a strong object-oriented model. Key features include an abstract geometry model for representation of detector components, a flexible track representation model, a built-in KALMAN filter for track parameter determination, and a powerful object factory model for fast handling of numerous small objects, such as hits and tracks. The new tracker will be deployed and used for analysis of data aquired during the RHIC year 3 run of the STAR experiment.
