Description

This package contains classes providing a simple simulation of the D0 central scintillating fiber tracking system (CFT). It has no dependence on the software used with that system. Classes with such dependence may be found in package cft_trf.

The physical components include:

SimpleCFTDetector( header, source, test )
SimpleCFTDetectorSimulator( header, source, test )
CFTPathBuilder( header, source, test )

Their dependencies are illustrated in the physical dependency diagram.

The class diagram [does not exist] shows the classes and their relationships.

The file cft_path.obs is an objstream description of a path for finding tracks.

The integrated test read_path.cpp demonstrates the use of and tests the readability of that file.

This package depends on the following external packages:

trfcyl - TRF++ cylinder extensions
trffind - TRF++ finding classes
trffit - TRF++ fitting classes
trflayer - TRF++ layer classes
trfbase - TRF++ base layer classes
trfutil - TRF++ utilities
spacegeom - Space point and vector
ptr - Pointer classes

The following sections describe the main programs and the classes defined in the components. Unless otherwise, noted each class is defined in the component of the same name. The descriptions here are brief. See the header files for details.

Detector

Class SimpleCFTDetector describes the CFT detector as 16 LayerCylinder layers.

Class SimpleCFTDetectorSimulator uses HitCylPhiGenerator or HitCylPhiZGenerator hit generators to generate hits for phi and stereo layers, respectively.

CFTPathBuilder

Class CFTPathBuilder appends a path tree for the CFT detector to an existing path.
