4347b38f 22//
37c4363a 23// Forward Multiplicity Detector based on Silicon wafers. This class
9f662337 24// is the driver for especially simulation.
25//
26// The Forward Multiplicity Detector consists of 3 sub-detectors FMD1,
27// FMD2, and FMD3, each of which has 1 or 2 rings of silicon sensors.
37c4363a 28//
29// This is the base class for all FMD manager classes.
30//
4347b38f 31// The actual code is done by various separate classes. Below is
32// diagram showing the relationship between the various FMD classes
1a1fdef7 33// that handles the simulation
4347b38f 34//

52// * AliFMD
53// This defines the interface for the various parts of AliROOT that
1a1fdef7 54// uses the FMD, like AliFMDSimulator, AliFMDDigitizer,
55// AliFMDReconstructor, and so on.
56//
57// * AliFMDv0
58// This is a concrete implementation of the AliFMD interface.
59// It is the responsibility of this class to create the FMD
60// geometry.
4347b38f 61//
62// * AliFMDv1
63// This is a concrete implementation of the AliFMD interface.
64// It is the responsibility of this class to create the FMD
65// geometry, process hits in the FMD, and serve hits and digits to
66// the various clients.
67//
1a1fdef7 68// * AliFMDSimulator
69// This is the base class for the FMD simulation tasks. The
70// simulator tasks are responsible to implment the geoemtry, and
71// process hits.
4347b38f 72//
9f662337 73// * AliFMDReconstructor
74// This is a concrete implementation of the AliReconstructor that
75// reconstructs pseudo-inclusive-multiplicities from digits (raw or
76// from simulation)
37c4363a 77//
9f662337 78// Calibration and geometry parameters are managed by separate
79// singleton managers. These are AliFMDGeometry and
80// AliFMDParameters. Please refer to these classes for more
81// information on these.
