User guide, system requirements,
installation instructions, and developer information
The TreeSearch library provides a highly configurable
module for the Hall A C++ Analyzer Podd. The module
performs high-speed track reconstruction for drift chamber systems
such as the one used in the Hall A
BigBite spectrometer. The software should be fairly easily adaptable
to wire chamber-based tracking systems of other spectrometers as well,
there are at least 9 wire planes: three ore more planes in each
of three or more coordinate projections (e.g. u, v, x);
the wire planes are parallel to each other; and
tracks in the tracking region are straight (field free region).
The TreeSearch algorithm has been successfully used for track reconstruction
at HERMES and has been proposed
for other experiments, such as Q-weak
at Jefferson Lab.
