20 | // Forward Multiplicity Detector based on Silicon wafers This class | |
21 | // contains the base procedures for the Forward Multiplicity detector | |
22 | // Detector consists of 5 Si volumes covered pseudorapidity interval | |
23 | // from 1.7 to 5.1. | |
24 | // | |
25 | // The actual code is done by various separate classes. Below is | |
26 | // diagram showing the relationship between the various FMD classes | |
27 | // that handles the geometry | |

54 | // * AliFMD | |
55 | // This defines the interface for the various parts of AliROOT that | |
56 | // uses the FMD, like AliFMDDigitizer, AliFMDReconstructor, and so | |
57 | // on. | |
58 | // | |
59 | // * AliFMDv1 | |
60 | // This is a concrete implementation of the AliFMD interface. | |
61 | // It is the responsibility of this class to create the FMD | |
62 | // geometry, process hits in the FMD, and serve hits and digits to | |
63 | // the various clients. | |
64 | // | |
65 | // It uses the objects of class AliFMDSubDetector to do the various | |
66 | // stuff for FMD1, 2, and 3 | |
67 | // | |
68 | // * AliFMDRing | |
69 | // This class contains all stuff needed to do with a ring. It's | |
70 | // used by the AliFMDSubDetector objects to instantise inner and | |
71 | // outer rings. The AliFMDRing objects are shared by the | |
72 | // AliFMDSubDetector objects, and owned by the AliFMDv1 object. | |
73 | // | |
74 | // * AliFMDPolygon | |
75 | // The code I lifted from TGeoPolygon to help with the geometry of | |
76 | // the modules, as well as to decide wether a hit is actually with | |
77 | // in the real module shape. The point is, that the shape of the | |
78 | // various ring modules are really polygons (much like the lid of a | |
79 | // coffin), but it's segmented at constant radius. That is very | |
80 | // hard to implement using GEANT 3.21 shapes, so instead the | |
81 | // modules are implemented as TUBS (tube sections), and in the step | |
82 | // procedure we do the test whether the track was inside the real | |
83 | // shape of the module. | |
84 | // | |
85 | // * AliFMD1, AliFMD2, and AliFMD3 | |
86 | // These are specialisation of AliFMDSubDetector, that contains the | |
87 | // particularities of each of the sub-detector system. It is | |
88 | // envisioned that the classes should also define the support | |
89 | // volumes and material for each of the detectors. | |
