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 |

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. | |
